User experience is very important and should be considered from the inception of a product. Saying that you are building a product for power-users but calling it “Simple BTC Wallet” is a bad start. There is nothing simple about this interface. Even if it had a few great features, they were lost in the clunky interface. Lightning adoption wasn’t the issue here.

Maybe are you replying to the wrong person/note?
Btw, I don't think SBW ever presented itself as "power user wallet".
I agree this is not the best interface for many details and of course was not curated by a designer (OBW is much better in this respect, at least on the colors palette), but call it "shitty" without even try it is a bit hasty, isn't? :) Download OBW, open an hosted channel for few sats and play with it. Maybe you can change your mind.
Which do you think is a great self-custody LN client? And why?
So far I’ve tried Breez, Muun, Phoenix, Blixt, and Mutiny. I’m a pretty big fan of Phoenix and Mutiny has a lot to offer, and I’m sure it will get better. I’m really pumped for what nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 just announced.
