Both as bad as each other if driven hard......
Both as good as each other if respected.....
I know 1 guy who had an Esc Cos and drove it hard all the time and regularly broken it and also have a mate with an Evo 6 who also drives it hard and in less than 10,000 miles went thru 2 rear diffs, 1 gearbox and 4 clutches so anyone who tells you Evo's are bullet proof need to drive theirs harder
