No question about it: for you, get NEXUS. I just had my interview yesterday, and the officer asked if I also wanted Global Entry, I said yes, they signed me up for it and put the CBP sticker in my passport so I don't even have to go to a GE enrollment center. In fact, the ironic thing is I can use GE and Pre✓ right now, but have to wait for my card to arrive before I can use NEXUS. All this for $50!
The only reasons to get GE instead of NEXUS are if it's too inconvenient for you to go to a NEXUS enrollment center or if you don't want to give your info to the Canadian government. In your case, the NEXUS enrollment center is across town, so the first reason isn't an issue.
