I'll recommend to you what I purchased for my very first PCP. I did a lot of research and in the end, I chose the Benjamin Cayden in .22 and here is why.
Wanted to start out with a traditional wooden stocked rifle
decent trigger that you can adjust (Lots of how to video's online)
3000 psi fill, so easy to pump (keeps you in shape)
Accurate, very accurate, especially with the Crossman 14.3 pellets that are $7 per 500.
Simple and robust magazines that can be had for around $14 on Midway USA
Smooth side lever vs. a cocking bolt. it really is smooth.
Picatinny rail to make mounting scopes easy
Adjustable stock comb to make fitting you and your head to the scope height easy.
5 year warranty
cost, I scored mine from Airguns of Arizona for just under $500..
Only down side I have found , it's a bit loud, but a Moderator quiets it down quite nicely.
You could do a lot worse on your first PCP.
