Agreed, there is no overall "best" (which is why I never used that term). There could be a "best" wallet for my specific example.

I have my primary BTC stack in cold storage. Why would I have multiple LN wallets when that comes with lots of overhead in channel fees, etc?

What are the features that are in Blixt or Phoenix that aren't in Muun? Your article is invalid since you put Muun in the custodial camp. Just because you don't understand how they use 2of2 multi-sig doesnt make it custodial. The only part of the app that has a brief amount of custodial action is the turbo channels option, and you can turn that off if it concerns you.
