Minibits has "keys" for you to recover from the funds in case you loose your phone or uninstall the app. It does NOT prevent rugs, or the mint just going dark. Same thing with WoS. The difference is that with mints you can choose the mints you trust. If a friend of yours runs a mint or even a local business that you know, maybe you can thrust them. The only LN wallets that protect you from rugs are self custodial wallets, some of the are Phoenix, Zeus, and Mutiny among others. But these you have to deal with fees to open channels an manage liquidity. One advice I give is use a custodial wallet, and if you get to a point where you have many funds there and are worried about losing them just send them to onchain or to a self custody LN wallet.
