T&B, have you noticed any mechanical differences between those two? Is one slower/faster, run more quietly, etc.......?

I just ordered a HL 1/16 Pershing S&S last night, so I'm gonna take a week or two and decide which 1/24 I want to get. I really like the Leopard more than the Abrams.... It just has an ominous look about it! I don't think I like the way they rigged those headlights and tail lights up though..... How they start and stop all the time..... weird.
