Given the exact same NFT (same art, same price), does the network its on affect your minting decision?

Conditional logic tree 

if investment, yes
- if not investment, but mint or transaction cost, yes, absolutely.
    - if no mint/txt cost, less so, though I'd care as far as wallet support goes (who displays it correctly, does it show up on rainbow.me/zherring.eth or do I have to go to OpenSea to check yada yada).

TBH network incentives can also have a bit of a play on my mindset, just depends on how manic I am at the time ;)

sometimes... but not too much, I mint what I like ultimately.

100% - network and minting fees are a big factor

If I'm planning on speculating the NFT, then yeah, I'd want it to be on a chain I believe will have adequate volume and eyes on
