I cast my vote for Reaction, as a nod to the RT team for Gantry and the future. I am building a site for a church right now using Reaction and it's coming together really well.
I loved Infuse's subtle detailing and shaping around the mainbody and modules. Wasn't as crazy about the distinctive backgrounds and haven't found a way to use that template yet, despite spending some time trying to bend it to suit a couple projects.
My second choice would be Moxy which I used to create a beautiful site for an art gallery, and it seems like a very flexible, adaptable template.
I haven't used any of the other templates. (But that's my own fault -- I'm such a slave to Versatility 4 and Hivemind; I keep going back to those all the time!)

I voted for infuse as it gives you more ways for using it for different needs.
I really hope you will update it for gantry, this would be great!
For 2010 i hope we can see some clean templates, more preset styles and module variations so we have more possibilitie to use them for different things
Maybe not as much eye candy or cool features as some of the other templates ...
But from a moderator's standpoint (as well as a developer's) being able to move your content around exactly the way you want it, where you want it, without having to hack the original code to add positions...
