Leave higher paying job for lower paying with pension ? : personalfinance

Hello all, Im 37. I was looking for some finance/employment advice. I make around 130-140K/year with a tiny pension (Ill probably have 200K when I retire) and a solid 401K (company puts in around 15K/year). I was looking around a found a position that will pay me around 80-90K, with a small 401K match (I put in 6% they put in 3%) BUT they have a good pension (I would end up walking away with 60% of my best 3 combined years).

What is my best deal here?
