RSK does appear to be a good system and I will say Ive been looking at it quite a lot recently. Whether it will get mainstream adoption only time will tell. On a negative side , Im not sure how people would feel about that its not decentralised and that you would have to lock in/ trade btc to use it. LN can be used for payments, but LN cant be used for other contracts.
What do other people think, any more information would be helpful.
Sorry OP havent helped you much.
