I started with Casa, and I did like them. But I moved to Nunchuk's collaborative custody for reasons I've forgotten. I think Unchained also has a similar product.
Discussion
Something I didn't realize until just now: is it possible to initiate transactions and fully sign them _without_ Casa's involvement? (Say their service is temporarily offline).
Did you have any experience with using your two keys without involving Casa's key? How cumbersome is that workflow?
Yes, they provide instructions for how to do that. You basically import the wallet into Sparrow wallet on desktop and connect your keys to it. It's more involved than that, so you should practice doing it.
