Green is pretty close to being the optimal Bitcoin wallet for most people imo. 

-LN with splicing
-Liquid (secured by Jade/2FA)
-Base chain (same as Liquid, also has 2/3 ms that I believe is similar to Bitkey's model)

PSBT is one of the key things it's still missing. Once they get that and swaps between layers within the app (Boltz?), they'll be on fire. Hopefully soon!
