The "Center-Point" scopes are made by Crosman at a low price point and are supposed to be rated well last I heard, not super great but good enough... pretty much everyone's go to is the UTG Bug Buster scopes but they are above my pay grade for as many toys as I have...
The maximus is fine accuracy wise, I don't shoot targets unless they are feathered or fuzzy mostly or just screwing around... I get bored shooting paper too easy...
Pretty much every PCP is hand pump friendly, it's just how much effort you want to put into it, my first PCP was the .22 Marauder that was "refurbished" with a refurbished Benjamin hand pump, took a bit to pump up but was doable, that's part of why I got it tuned to where it ended up, 60 shots at like 850fps with crosman hollow point pellets. The maximus being a 2000psi fill pressure with a lower volume is obviously easier to pump up... the Avenger is like 4300psi fill pressure and I've hand pumped that a few times...
I have no idea on the recoil part, but my engineering mind says it'll likely be similar if the muzzle energy is similar with the whole equal and opposite force deal
