There are many reasons why I prefer gaming on a console (PlayStation this gen and last, XBOX 360 before that) rather than on a PC.
Convenience / Ease of Use
Consoles are always hooked up to the TV ready to go. Just plop on the couch grab the controller and you're gaming in seconds. UIs are usually pretty straight-foward and do a good job. No separate storefronts or launchers, no drivers to constantly update, it's just much simpler in general.
Gaming on a big screen TV
Most people don't have their gaming desktop PC in their living room so you can't always play on the big screen and if you want to you either gotta move it or have a long HDMI cable depending on how far it is. TVs have managed to catch up to monitors a little bit thanks to HDMI 2.1 with features like 144Hz refresh rate, VRR and ALLM so console gamers can now enjoy these features on top of the big screen size. Even if you game on your TV using your PC, this is only due to consoles existing, because that's what pushed TV manufacturers to include such features.
I prefer to game using a controller rather than mouse/keyboard
Controllers just feel great to me, particularly the DualSense, I love the haptics. Aside from Football Manager and RTS games, mouse+keyboard gaming just doesn't feel right to me. Thankfully PC games have been supporting controllers for sometime now, with big publishers recently even including support for DualSense features when using one on PC. Playing any competitive multiplayer game using a controller on PC though will be challenging to say the least which brings me to my next point.
Online / cheating
Online may be free on PC but cheating is so rampant that it's not worth it to even play. You need to pay on console but the closed environment gives you a better shot at enjoying the online experience, plus you get 30+ free games per year with PS+, sure a lot of them are meh, but there's always a few good ones that make it worth the 5-6 bucks per month it costs. I'll admit that crossplay has definitely hindered console multiplayer and so has the advent of hardware based cheating devices such as the Cronus Zen. Overall I still enjoy the online experience more on console.
Games / Exclusives
Many games I enjoy are timed exclusives on PlayStation compared to PC, be it PlayStation Studios games or franchises like Final Fantasy and GTA.
Dealing with PC Hardware
If you game on PC because you want the best graphics and performance it almost requires you to update your hardware every 2-3 years at least otherwise there's no point. Even it you can afford it, it's costly and troublesome. Not to mention you can run into issues such as coil whine on a new GPU, which happened to me twice. When I was younger it was fun to tinker in my rig but these days it's more of a hassle than anything else. Upgrading a console is much simpler, just sell the old one and buy the new one and you're good to go.
Dealing with PC software
On top of all the launchers, drivers etc... I mentioned earlier, another issue I have with PC gaming is DRM software. Some like Denuvo have been proven to reduce performance, giving paying customers a worse experience than pirates. I had a very bad experience with one called StarForce back in the day when I bought Splinter Cell Blacklist. After I installed the game I noticed that my PC started to feel sluggish and crashed often. As soon as I uninstalled StarForce everything went back to normal. That's when I mostly gave up on PC as my main gaming platform and focused more on consoles. Launchers and other gaming apps have been shown to be spyware that collects data off of computers and people generally have their whole lives on their computer so it's not the same as a console gathering data on you. The games themselves often have issues too like micro-stuttering which isn't present on consoles. Games on PC are un-optimized compared to console versions which are designed to be run on specific hardware that is the same for everyone. PC ports are often an afterthought for publishers, as console sales will generate far greater revenue, an as such can be very poor.
The most important reason: Physical releases aka actually owning my games
If I'm going to pay for my games I would like to actually own them, be able to lend or give them to friend, or even resell them if I choose to do so. Digital doesn't let you do that, in fact you don't own digital games you just own a license to playthem which the supplier can take away from you at any time for any reason they see fit. So again, legit PC gamers are getting a way worse deal than pirates who can never have their pirated digital versions taken away. There is no convenience in digital over physical other than not having to get your ass up off the couch to swap discs, but with obesity rates the way they are these days, getting your ass off the couch can only be a positive. Paying as much or more to not actually own something while being at the mercy of corporations is ridiculous and I will think less of people who do it for anything over 10 bucks. This brings me to my last reason.
Pricing
Pricing for Physical games are way cheaper at launch than MSRP if you buy from certain stores depending on where you live. Even Amazon can be way cheaper than MSRP at launch sometimes. Physical prices drop much faster as well as stores and warehouses need to clear space for newer products. Waiting just 4-5 months for a sale can yield 75% off MSRP or more in most cases. There are ways to get new digital games for less on PC, but it often involves purchasing keys from gray market sites, which are pretty much stolen and for which, in most cases, the devs/publishers will not be compensated. I'd rather buy from real stores so I know the people who made the game are being compensated.
So there you have it, those are my reasons. PCs definitely have some advantages over consoles, but for me, the advantages of consoles have over PCs outweigh them.
