Thats pretty accurate.
Wanna go fast, get a Zerode, wanna do jumps and tricks on lower speed tracks, buy something with less rearward axle path. Having said that though, a good shock tune can make the Zerode more "fun". Rearward axle path is great for casing jumps though, if you're always going bigger, won't hang up as much.
All being said, there's no new Large Zerodes availabe for some time now. So grab that used one in the for sale section while you can.
Crankin(the Ozzy Zerode distributors) have Works Components reach adjusting headsets available for mediums though. Gains you 7mm, not much, but if you're on the fence.
Maybe check out the new Comencals if you can't get a Zerode and don't want a Canfield. Or buy a cheap old Balfa BB7 or Trek whatever they were called with the high pivot for cheap as an experiment.
