I have a Triumph and it shoots better than any other gun I have( and I have 8), I have a friend who has the Encore and I prefer the triumph. ( If you don't want to switch barrels that is). I have sighted mine in at 100 yards and with a BDC reticle have been shooting out to 200 yards no problem . It's dead on. Easy to clean and shoots great. It doesn't like powerbelts though but it loves the superglide shock waves , the Hornady FPB, Precison dead center, Scorpion Pt's and a few other sabots I've tried.
The Encore is a good gun so you can't go wrong either way, I just personally like the Triumph. Good luck on your decision
