Hope you've shouldered them first to see how they fit and balance on you. No experience with Hatsan. Some models you mentioned don't have stippling on their grip points (which would be a deal breaker for me) so definitely shoulder first. Lighter break barrels if you're going to be carrying it in the field all day. The 48 has the advantage of having a bit flatter trajectory being more powerful (needs a rock solid scope) but it's ratchet mechanism may give you away while loading. So maybe the 48 if you're bench shooting off your back porch? Or you could use lighter alloy pellets on the less powerful ones to keep it flat. Optional but whatever you choose, you may want to take it apart for a deburr, polish and relube. They'll all be overgreased from the factory as the manufacturers don't know how long the guns will be on the shelf. If you will, the 48 will need a spring compressor rig.
Based on your list, definitely the 95. That's definitely the highest quality one. Lot's of aftermarket tuning options too if you want to get rid of the twang (they all twang to a degree, even these supposedly tuned guns out-of-the-box like an LGV or TX200). The rekord trigger breaks glass crisp after you take it apart and polish the contact points of the sears with some autosol and proper lubrication (so does the T06 on the 34/48).
PS: If you're open to 177, there's a 97KT on sale in the forum right now.
. They all drop with a headshot, 177 or 22.
