I like mine a lot, but there's no comparing the HW80 to the Terrus, in my opinion. I compare it to my recently acquired RWS 34, which is a common relationship, it seems. I consider the Terrus to be a medium powered, moderately accurate or better rifle...in .22...but I consider my tuned, vintage R1 to be of magnum power...also in .22. They occupy two different stalls in the stable. My R1 is a laser...not so much the Terrus, but I'm still working on that! I definite feel that I got my money's worth.
I'm not familiar with Crosman or Hatsan...the only Crosmans I have are a couple of Quest 1000X's in .177, and neither of those are in my serious shooting rotation...as I don't care for the caliber. I have toyed with the idea of getting a Hatsan Dominator or Torpedo, but that's up the road, if ever. Because the Terrus is a German wood and steel rifle, in my own mind, it's in a totally different league than the Crosman, Hatsan, or similar. Others may disagree, but that's just the way I feel. I may change my mind if and when I get a Hatsan.
