Never had the pleasure of handling the Temperance, but I can tell ya' that it's awful darn hard to go wrong with the Perrin. I've had mine since March and have used it for every darn thing I can think of, and it always does excellent for utility. I've cut wood, rope, lotsa carpet, leather, cardboard, cloth, etc. I even did some prying up of nails with the blade tip that should have busted it, but didn't. (just to be clear, if it had broken, I would have taken full responsibility for my insipid actions, Spyderco did not market it as a pry bar) I've used it for just about every task i can dream of and it is EXCELLENT it carries very well and comfortably EDC. I carry mine with the plain, boring factory sheath in a reverse grip draw with the tip of the sheath actually sticking into my pants pocket a little bit with my T-shirt over it most times. When carried with my SAK Tinker I just couldn't imagine a knife task I couldn't take care of. It also holds an excellent edge, it's light, flat, perfectly sized, It has excellent retention qualities in a Philipino grip, it's reasonably priced....
Have I mentioned that I really like this knife?
I haven't used it to ward off any attackers yet, but with that awesome grip, large blade (cpmparatively), and razor sharp edge I got no reason to believe it would perform poorly.
I could not imagine a better fixed blade knife for myself, although I did just get a Ricky Fowler that I'm awfully darn enamored with, but..then again you're talkin' about a $300 knife versus an $80 knife. nine times outta ten when I reach for a knife for EDC, Protection, camping, or anything else it will probably still be the Perrin though.
Sorry I can't give more of a comparative analogy with the Temperance, but in my honest to God middle class knife guy opinion, that Perrin would be awful darn hard to go wrong with.
Have a good day, and let us know which you choose, and how you like it, eh?
