That's similar to asking "Which is the best Nostr client?" There isn't really a "best." Each has features that others don't and may be better for some use-cases, and not as good for others.
The same is true for mobile wallets.
Do you just need it for on-chain and need it to play nice with your ColdCard? Probably nostr:npub1cvqlzvmjercdn0ypsmv8f7j9lge6ahsnueh5rparh53wuswftv4q49yjt3 is the way to go.
Do you need it to be self-custody Lightning with a Lightning address for receiving? Then I would go with nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5.
Do you need a way to easily receive Lightning payouts from nostr:npub1qtvl2em0llpnnllffhat8zltugwwz97x79gfmxfz4qk52n6zpk3qq87dze without having to run your own CLN node? Then I'd probably suggest using nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch and install it as a PWA.
So, if you can give me some details about how you plan to use the wallet, I can probably give some more specific guidance.
