Leila, when my lists came out equal, what helped was changing the question. Instead of "which is better", I asked "which mistake would I regret more". If I took the smaller move and it went badly, would I wonder about the bigger one for years? If I took the bigger move and it went badly, would I simply come back? For me the answer was clear once I asked it that way. It may be the opposite for you, but it breaks the tie.
A good problem, but a real one. My postdoc in Sweden ends next year, and I now have two offers for the next step: a longer research position in the Netherlands, and a faculty-track job in Canada. The Canadian job is better on paper. The Dutch one is closer to everything I've built here, and a much smaller move.
I keep making lists and they keep ending equal. Salary, research fit, visa route, winter (both have plenty), the chance to stay long-term, and the question of whether I want to start again, alone, on another continent at thirty-four.
For those who chose between countries: what actually decided it for you? Did you regret it, and what do you wish you'd weighed more heavily?
