Nintendo Switch.
My wife bought a refurbished Wii U when we were newlyweds, and I loved it. I know it had its warts, certainly, but the first party library was amazing and the Wii U generation, along with my 3DS, got me back into Nintendo after I spent a long time away from their systems due to life circumstances and college. I'll never forget the launch weekend of Splatoon, or the agonizing wait for Xenoblade X, which ended up meeting the impossibly high level of hype I had carried for it for years.
When NX was announced and the Switch unveiled, I knew Nintendo was going to have a hit on their hands, based on the awesome Wii U first party games, and I was desperately hyped up. It is was the first console I ever pre-ordered for launch, and those seven weeks between the January 2017 Switch presentation and the 3 March 2017 launch date were like...excruciatingly hyped for me. If that makes sense. I felt like Cartman trying to will himself forward through time for the Wii launch on South Park.
And the Switch met the hype, and completely exceeded it for me. My favorite console of all time.
