I think you will end up being happy with whatever you get and if you get a macro lens and decide you aren't using it as much as you'd like, you can always sell it and probably make back what you purchased it for.
Truthfully, I purchased the Nikon 60mm f/2.8 micro a while back and found myself always using it as a regular general purpose lens and not a macro. I just wasn't patient enough for the whole taking the tripod out, trying to wait for a flower to stop swaying in the breeze, etc. I ended up selling it and making my money back and eventually landed on the 85mm f/1.8, which I'm really happy with now.
I've had UWA, fisheye, telephoto, zooms, primes, macro, and all-in-one lenses and I think that the best way to figure out if you'll like something is to try it out for yourself, you never know what you may end up liking most.
