I have spent much time doing my own investigation and came to the conclusion that I don't have enough information to predict with absolute certainty the best path forward in the long term, so I choose to keep all forks. I am a long term holder with no intention to ever sell my coins.
Don't bother arguing with these fools as 99% of them are too lazy to have done any due diligence themselves and just hope that someone else will work on bitcoin and it will somehow make them rich. From memory, when I did the estimates way back in the day, I think I came up with bitcoin needing 8 MB blocks in the long run to function as a global settlement system where transactions of around $10k or more are viable.
Is 2 MB blocks + LN equal or better to that? No. LN is an even more centralized, more permissioned version of bitcoin where they seek to transfer all consumer payments to. So you theoretically CAN transfer most bitcoin traffic there, but LN doesn't actually have anything in common with bitcoin in the first place. It's a totally different system. It's like replacing bitcoin with bitshares and pretending it's the same thing. But when it comes down to it, bitcoin transaction validators are designed to centralize, nullifying any reason for it's existence, so there's no point in even discussing building any 2nd tier layers on it.
Discussing LN vs bigger blocks is like discussing what color to paint the Titanic. It's 100% impossible to create a decentralized digital currency where transaction validators don't centralize.
