First, decide if you want 2wd or 4wd. If you want 4wd, you should probably get the Slayer. I've never run the SC10, so I can't tell you how durable it is. I do have a Rustler, which is what the Slash is based off of, and I beat the crap out of it. Being as the Slash is based on the Rustler, upgrades should be easy to find. Out of these three, I'd recommend the Slash.
