I can't speak for the colt cause I've never shot that particular one, but I've had several trp's and they're very good shooters. One thing to note on the springers is the front checkering, it's very aggressive. 20 lpi iirc I like it keeps the thing planted when you start sweating.
DEPENDS ON WHAT YOU ARE GOING TO DO WITH IT ! YOU GET THE MOST OUT OF THE TRP ! ITS A BETTER SHOOTER AND GOOD DEFENSE CARRY GUN. IVE GOT THREE GOLDCUPS AND THEY DO FINE WITH MATCH AMMO BUT IF YOU ARE GOING TO CARRY IT AS DEFENSE GUN ID RECOMMEND SPENDING SEVERAL HUNDRED DOLLARS TO GET IT UP TO PAR ! JUST MY OPINION. I SHOOT MY SPRINGFIELD A LOT MORE THAN THE COLTS !
I know it's not one you mentioned, but I'd take a look at the Dan Wesson Valor and Specialist in the price range of those two. I'd go DW, TRP, then Colt.
I found myself in a very similar situation a couple of years ago. Dan Wesson or Colt Gold Cup Trophy. Not sure if you'd consider DW, but they're awesome guns and Series 70 as well.
