The Venom accepts standard sized Japanese parts, but in order to swap out the joystick you will need to replace some cabling. It's an easy fix if you've messed with replacing cables before. If that doesn't deter you, it's a pretty good budget stick. As far as using it on PC, there a bunch of different ways to get things working with 3rd party apps akaIk.
The parts they use are knock off Sanwas though, and I personally would not use them for a long time. I especially would not use the joystick in it if I were a shmup enthusiast. The Sanwa JLF is already fairly unpopular with shmup players, and it only gets worse on the knock off. The main problem with the JLF is the deadzone and throw are pretty wide, which is pretty annoying when doing pixel perfect movement in shmups. The knock off thing in the Venom is worse about this around the corners. Unless you plan on changing that thing out yourself relatively soon, I honestly wouldn't recommend it for shmups.
The Hori V4 Kai is pretty nice and goes on sale often enough. The Hayabusa buttons are nice and I'd say compete with Sanwa/Seimitsu while also being distinct. The sticks have native Xinput support on PC. The Hayabusa joystick is very similar to a JLF in a lot of ways, for better and worse. It's a much better stick than the JLF knock offs and is perfectly fine, but it still has some of the same issues as the JLF in regards to shmups. Luckily the HRAP uses a standard harness, so if you want to swap out the stick at some point it's as easy as getting a new one for $20~ and screwing it in the mount. The cases on these HRAPs are a bit light for some people though, but ehhhh I've used them and don't mind it.
So yeah, it really comes down to how high quality you want and what you plan to do with them. If you want something that is high quality out the box and can easily have parts swapped in/out, go with the Hori v4 Kai if you have the budget. It's a great starting stick. If you want something on a budget and you think you could upgrade it later, the Venom is fine, but keep in mind those problems out the box.
Edit: While I was rambling about the JLF and shmups, I should mention it is a great joystick for fighting games. The Hayabusa is also great for fighting games, and IMO it's a bit better for shmups over the JLF. I'm sorry if this is all way pickier and more than you need to know
