Stop in for a cup of coffee

Good afternoon.

So I find myself in a brief dilemma. I had accepted a position last week that gets me out of this current hell hole. That position is essentially identical to the one I’m leaving. IE drafting and design work.

I mentioned last week I’d received a competing offer but that offer was way less money despite being in a project manager role, which is what I want long term.
Well I turned that offer down. Then yesterday, that company’s head HR lady called me, we spoke for nearly two hours, today she’s sent me an offer that matches and in some areas exceeds, my first offer from the other company.

So now, I’m torn, stick with my original since I already accepted or take the latest which is ultimately where I want my career to go

I guess two things

1. What is the burned-bridge blowback if you turn off the initial offer?
2. I've gotten into the mode of "Better, not just different", so is # 2 truly "better"?

Big picture, take your career where you want to go otherwise you'll kick yourself down the road.
