HCP, after you experiment with this wallet, can you compare it with Electrum Android?
I have to admit that this is first time to hear about this wallet, and it seems that this is a very serious project. For me (and probably anyone else) is important that users is in full control of private keys. It is also nice to have LN support, some people tested this some 6 months ago on this wallet and everything worked perfectly - means that today it can only be even better.
I've been testing Blue Wallet on main net for almost a week now. I tried every possible service with incoming and outgoing payments. I converted BTC with zigzag back and force, I tipped here, I used yalls, I played multiple games, and used maybe a dozen other things multiple times. I tested with anything and anybody I could find. The LN payments worked every single time, never failed once. On average payments took 1-2 seconds, feels much faster than a credit card. Scanning QR codes was painless and fast. I didn't have to fill out anything, like with credit cards, I didn't have to worry about my information stolen, or the amount to be incorrect. I could pay as small amounts as fractions of a cent. It was a really pleasant experience overall every time.
I know Blue Wallet is custodial, but the objective of the testing was to see if LN can be a reliable method for everyday spending. And I can categorically say that it is. It's better than any other payment method in many ways. I highly recommend you trying it out as well with a small amount of funds.
