I would choose the one that in my heart I know I'd go to as often as possible.
I recently moved and the new gym is so different from my other gym. It's smaller, the machines are old and don't have tv-screens in them and there is no good guidance. I can't use an electronic key and load it up and just follow it. I don't see my progress. And for me, that was what I loved about the other gym. Get there, do what the key said I had to do, watch some tv and go back home. This figuring everything out myself and so on is not working.
I am cancelling my gym subscription and just bought a few things for at home. The other gym is in another city and I can't go there, so I am just gonna make do with home stuff. Since I barely go once a week to the new one, where I went atleast 3 to 5 times a week at the old one.
So, pick the one you KNOW you will go to. And I mean FEEL-KNOW. Not rationally thinking you know. Because it doesn't work that way. Hihi.
