Great response from @DarthCoin in another thread below: ā€”-
WoS is simply a bank, giving you an account. Nothing more. Is it helpful? Yes, in some level is good to onboard easily noobs. But not to use it forever only.
Bluewallet is a lndhub provider, so again user have only an account and use the BW liquidity. Is it helpful? Yes, again in some level. What's interesting is that you can run your own lndhub node and offer to yourself or to your family lndhub accounts in a more trusted way, not depending on BW servers.
OBW is a node on your mobile, but comes with an amzing feature of hosted channels (also with normal channels). Again this is good feature easy to onboard noobs. You can run your own Poncho server and offer to your family and yourself HC, Read the guide I sent you.
As you can see are many ways to use LN. And as I said in my guides: important is to choose the right wallet app for the specific situation and use multiple ones, not just one. Each one have its own use case.
