I just finished a playthrough of the Switch version a week ago, in an effort to determine if I wanted to gift my best friend this or another version. After attempting to start with this version shortly after launch, it feels like night and day compared to it's initial release. They've done a great job with getting it closer to the other versions.
That said, I can corroborate what others are saying. The game does occasionally stutter, and the load times can be hit or miss. Some areas will load in the blink of an eye, others can take 5+ seconds, something that is noticable if you repeatedly re-enter some rooms to farm drops.
Lastly, and this is my personal major complaint, the game crashes a LOT. Like, crashes three times in a five hour play session quite regularly. It got to the point that I was starting to get a feel for when it was going to happen, and it seems tied to the menu system and UI mostly. I could play for a while with no issues, go talk to an NPC and have it error out to the home menu. Couple that with the load times to get back in, and it got rather aggravating after a while.
Overall, it's very playable, and fully completable. It was a rather enjoyable playthrough, but I don't think I'll be using this version again.
