I think it's time.

Ok so, i have played all of borderlands. From first to tales. All except 3, and I'm thinking of buying it because recently my fiancé and I got into playing through them together. So I want to ask some questions and get some feedback. I heard it's the worst of all of the games. I haven't dug into it. But what do you all think? Is it worth it? How different is it and why? Who is the best to play and what's your favorite builds? Is it really the worst one?
Appreciate it
