Have owned tx200 MK3 .22 TX200 MK2 .22 and curently own a TX200 MK1 .22 and also have shot a TX200HC in .177.

personaly i think the early TX200s are slightly better than the MK3 not sure why just seem to be, but accuracy wise the .177 HC i tried was spot on accurate, not having shot a .177 in about a year was suprised to be hitting ping pong balls at 70 yards! (least i was once i realised not to give it the hold over of the .22 LOL) the recoil seems to be a little more refined on the HC i tried, compared to the short sharp recoil of the MK1/2 also has a few less rathcets on the anit bear trap so a little less noise there as well.

I dont think i have ever heard anything bad about the TX range at all

have to say it would be a close call over the

but should say have just bought a second hand pro sport in .177 and this beats any of the tx200s i have ever owned or shot. In fact it has very quickyl (in less than 24hours) become the best rifle i have ever owned.

hope this helps you out a little

PS weight wise i swear blind that my mates TX200 HC was lighter than my TX200 MK2 and he swears blind that his TX200HC was lighter than my TX200 MK2, so i think fropm that you could safly say they weigh around the same just slightly different ballance.
