I have owned all three. The STW is the hardest kicking medium rifle I've ever shot and could not get it to beat the Remington by much. I would go 7mm-08. Light kicking in lightweight rifles and good out to 300 yards.
I picked up a 7mm-08 in a youth model for my kid. I took it out last weekend and sighted it in. Wow I was impressed! I think with how light it is and even being a youth model with the short stock I might us it for pack in hunts. It's much more lighter then my 7mm
