I bought these after watching a Wulff Den review [cite] and absolutely love them. Bob gives an accurate take imo.
Split pads are GREAT for portable if you have adult-sized hands (all of us?). However, this is coming from someone who hates using joy-con in portable mode. I really dislike the small size of the thumbsticks.
If you need a carrying case then check out the ButterFox case specifically designed for these. [cite]
If you're between these and the Satisfy grips then skip to 6:14 in Bob's video cited above for great comparison. He goes into how you can use the assign and turbo buttons earlier in the video too. Love his channel.
Note: These don't support gyro and rumble
Here's a previous thread if anyone is looking for more info
Also here's a decent case for these

Yes. I don't know what the switch joycon case was but this was the hori case that I tried and didn't work either. https://www.amazon.com/ButterFox-Nintendo-Switch-Controller-Dockable/dp/B0899NBQVV/ref=asc_df_B0899NBQVV/?tag=hyprod-20&linkCode=df0&hvadid=459530536279&hvpos=&hvnetw=g&hvrand=79424044110177234&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9004357&hvtargid=pla-940809769828&psc=1®ion_id=373786
