2 is definitely harder. I didn't have modded weapons or dupe in bl 1 and it was still fairly easy. Im not great at shooters either. Imagine having a hellfire or defiler every 10 levels or so. Crawermaxx is still right up there with the raid bosses though IMO.

Borderlands 2 TVHM is definitely harder. PT1 is about the same difficulty as Borderlands 1 overall. But I think Borderlands 1 was so easy because fire weapons could obliterate anything, even shielded or armored enemies.
So I don't have to say this constantly I'm from South Africa, I wait a month or 2 after Europe to get new releases
