Yes, playing a souls-like won’t be an issue if you’d be happy playing on a regular game controller. Button position takes a little getting used to, but is much improved from the steam controller. Much more comfortable than using the switch IMO, due to better stick placement/feel, and thicker grips.
Actually only bought 1 and that was really just archival as I’d already played it on another system. Recommended a lot of things I’d played and enjoyed to others though. The things I’m still holding out for weren’t quite deep enough for me to pick them up just now.
