Thank you for your comments. EricL, no, the new job is only a few blocks away from the current one, so there won't be any expenses associated with the move.
We are not close to our ER yet, but are working on getting to FI. Pension is about 5% of my yearly income, so I try not let let it be a deciding factor.
I am planning on working for the next at least 15 years. SO work happiness would be important, but it is hard to compare. I am not particularly happy at my current place (various reasons and it was basically the reason I started interviewing in a first place). However, I cannot currently assess how happy I will be at the new place. Based on my LinkedIn research, people tend to stay at the new place for a while, so it is giving me hope...
