I've been trying out Temper a little and this is what I've noticed when comparing it to Mednafen:
It's more optimized to run faster without overclocking, so your battery will last longer.
Of course it doesn't support zip compression, so you will have to use bz2 or uncompressed roms.
The one arcade card game I have ripped (which works in Mednafen) freezes during the intro screen, but I don't know why. It might have something to do with the format (cue/iso/ogg), though that format I believe should work.
While mednafen supports toc/iso rips, you have to convert them to cue/iso for temper (not a really big deal since cdrdao includes the toc2cue utility).
