correct me if i'm wrong, verge is pretty much just bitcoin via tor? ...
No.
Try making any transfer in these 2 coins and then compare the speed and transaction cost. Verge is faster and cheaper.
I'm not badmouthing Bitcoin, it has come a long way which is fantastic! However, there are better crypto coins out there suited for payments. BTC scaling issues has confirmed this. Verge is a better option and you can choose to be 100% anonymous.
