I would cast a vote for the Benjamin Discovery. It brought pcp in for the masses. Cleaver design uses only 2000 psi so easy to use with a hand pump. Very cheap (for then) price
Also now, some PCP can use Nitrogen air. Not cost effective but good for hunting or emergency use.

Let me put it another way, they (most anyway) put these cheap throw away scopes on a gun. Instead give me open sights. If I need a scope I would probably have buy a decent one anyway. Just me.
I am a seasoned open sight shooter. Open sights have always been my favorite (yes even at longer ranges). But I now have an air rifle without open sights (🤬). I put on the cheap scope that came with the gun. I see the barrel (blurry) when looking through the scope. Is that normal? I took it off...
I don’t think there is a loser in the field. All are good. Much of it boils down to personal preference. Yes I like the 50 too. It’s a tweener gun. Sits between the 30 & 95. Maybe best gun it you could only have one gun?
