everwears hands down. i ride about 20-30 miles a day brakeless.. which includes a lot of stopping and starting. (courier in century city)... 42/16 ratio ( 8 patches )... but that number is useless if you can skid w/ your cranks at multiple points in the revolution. hence, my rear wears down evenly... i keep my rear at 140psi at all times.. this is crucial... lower pressure, wears your tire down quicker...

*drumroll*
my rear lasts for a good 1 month of work.
