I own a PS Vita (used mainly for emulation), which I rarely use after I've bought my Switch Lite and a Switch Pro Controller.
I love playing games on my Lite using the Pro Controller, and a standing base for the Switch, as it makes it more comfortable.
If you want to play recent Nintendo games, I do recommend a Switch Lite, easy to carry out, and hold when playing, even more if you get an ergonomic TPU protective case, it really improves the feeling.
As an extra move, I've replaced the joysticks of both, the Switch Lite and the Pro Controller with TMR joysticks, I'd say its really worth it.
