Getting the opportunity to test shoot some guns before buying is always the best case, but many times it just isn't feasible. And anyway you would want to have and shoot the gun for a couple of weeks or a month to really understand whether it is right for you (although there are a few which I have shot, and, unfortunately, immediately understood that they were not what I wanted). There are others which I have shot (especially bullpups) where I couldn't seem to hit the broad side of a barn at first. But with continued shooting one can reach an understanding of what that gun likes as far as hold, etc., and they can become a new, tack-driving favorite.
Also, and especially if you are anything like me, don't believe that these first 2 (long and short) guns will be your last airgun purchases. This hobby can be very addicting (my investment guy already calls me an 'accumulator' regarding all of my hobbies), and you may find that you want additional air guns for different purposes in the future. Or you just can't get on with something you bought, and it just isn't meeting your expectations. In this latter case, the used airgun market is strong for quality guns, and you will generally be able to recoup a major chunk of your purchase price selling it on the AGN Member Classifieds.
I had sworn (again) yesterday morning that I was through spending money buying new (well, most are used now) air guns. I already have some wonderful guns in my collection, and could now wait for that killer deal, or something really different & unusual before I would buy anything more. Then AOA drops a truck-load of pre-owned guns onto their web site yesterday afternoon, and now I have a new (used) long and short gun coming next week. D'oh!
It is too bad that you aren't local to me as I have a lot of air guns which you could try out (one of my buddies from Cowboy Action Shooting tried one of my air rifles at the range, and I didn't see that gun again for 3 months!). Do you have any local stores which stock and sell quality air guns (sure wish I did)? Are there any airgun clubs local to you? Some AGN members have also posted on this forum "Any airgunners local to XYZ area?" for possible meet-ups and shooting together.
You are new to the airgun journey, and you have done the correct thing to ask the collective wisdom of this group for recommendations before you spend your money. You are wiser now because of that, but you will still find things which you love or hate about specific guns, regardless of how others feel. And you may find that gun which all others have described as a dog, but just totally clicks with you. Hopefully it will be a long journey for you, with many interesting twists and turns, and much joy. That is definitely how it has started out for me (I really only seriously got into PCP air guns last July because they are something my wife and I can do at home to maintain sanity during the pandemic, with 25 and 50 yard ranges in the back yard).
Good luck, and let us know what you finally choose.
