Cam/lifter life - flat vs roller?

Is there a big difference between cam and lifter life in flat vs roller lifter setups?

With flats requiring a break-in period and maybe even the heads coming apart to change springs after break-in, and rollers being able to run steeper lobe angles - I can't see any reason to build a new engine with a flat tappet cam except saving a little on cam and lifters?
