For the OP, I'd go with GMRS. It is simply more common in that niche and the point is to be able to talk to other people stuck in the same niche with you. You can also talk with non-licensed FRS people, and if you wanted to you could pick up a 4-pack of FRS radios for about $30 and equip everyone in your vehicle with a way to keep in touch if they wander off. I mostly use my GMRS handhelds at the boat ramp or when working on the roof. I've never found a GMRS repeater in the wild, but I also haven't been looking for them much. I mostly like that there is basically zero barrier to entry for other people to use FRS and not much more of a barrier to use GMRS. The biggest downside is that your GMRS call sign will be long and hard to remember.
I also have my amateur general license, which I got a few months ago after a couple years as a technician. I'm stuck in radio shopping hell, though, because I can't define my mission well enough to pull the trigger on an HF rig. I do have a VHF/UHF HT (FT-60R) and I've thought about keying up the nearest net (it's a linked set of VHF repeaters, the nearest of which is 30 nautical miles from my house but line of sight due to terrain) but I haven't really pushed the PTT button much on it. I think I'd get more mileage out of a mobile dual-band in the car. Even more so in the plane but only if it could interface to the intercom, which is enough of a hassle to not do.
What I want to do: Learn Morse Code, get an Elecraft KX2, and have a rig I can easily put in a suitcase or backpack and use to make DX contacts on voice and HF when I'm traveling or hiking in the boonies. What I have time to do: Carry the FT-60R in my car and think about turning it on.
