I've owned a HW30, 35, 50, 77K, 80, 85, 90, 95, 97K, and a 98. Were I to own just one in 22 and I was buying it today, I'd buy a HW95 from D&L for $490. There isn't anything you can't do (within airgun limits) with a HW95 and it's the shortest and lightest in it's weight class.I'm sure you will find the accuracy excellent.
The 85 is basically the same gun just a different stock (a little fancier) and has a longer barrel.
The 35E is definitely "prettier" or classier (been in production since the dawn of time) and can be considered more accurate due to the barrel latch but the power is much lower.
The 77 and 97 weigh much more and are more accurate. But if you are that concerned with accuracy then you should get one in .177 to really squeeze out that last bit of accuracy.
The 80 is a slightly bigger version of the 95 which makes it more powerful (not a lot) but it's heavier and if you only have one gun the extra power isn't worth the weight.
The 98 is a 85 with a different stock and barrel sleeve so it's heavier and has the same power. In my mind it's a wanna be target gun that isn't, since it doesn't have a barrel latch.
The 50 is smaller and lighter but much lower in power.
The 30 is even smaller and lighter again but it's under 500 fps in .22
Which one do I own you ask? Well if I were a one gun hunter I'd get a 77K in .177. You can hunt with it, shoot Field Target with it and pellets are cheaper. Plus it has iron sights or you can scope it. Were I to buy it new today I''d probably get one of the Special Editions from Specialty Shooting. However I am not a one gun hunter so I have a HW30 in .22, a 35 with 2 barrels (.177 original and 22K) and a 80 with a .25K and a .22K barrel. My "one gun" airgun is a TX200HC (no iron sights) in .177.
The 85 should last you your lifetime as well as your kids. You can get aftermarket springs, off set triggers, different stocks (the 85 and 98 fit) plus there are custom stock makers out there. A 4-12 Bushnell Banner will work fine on it so will the old steel tube Weavers so scopes won't cost a lot.
My 2 cents. Hope it helps
