I highly rate Conti's for wear - my crosscountry/baja tyres, which are well over 5yrs old, are still going strong. They take any amount of slashes form sharp rocks and have great puncture resistance.
Amittedly, I ride on Panaracer XC fire pros at the moment, a great performing tyre, but very prone to cuts and thorn punctures. They won't last as long as the Conti's!!
