I don’t like ffp scopes, I can either get the reticle or the image in focus but never both together, I get eye strain if I use them for too long.
Nice gun by the way

I don't want to take this thread off-topic, but it sounds like the Ocular (Eyepiece) isn't correctly set. The Focal Plane doesn't factor in to the Ocular/Eyepiece adjustment. When correctly adjusted the reticle will remain sharply focused regardless of the magnification and parallax settings. Setting the Ocular/Eyepiece is extremely important, and is the very first thing that should be done after setting the fore-aft position of the scope for best eye relief.
Once properly set for your eye the Ocular/Eyepiece should not be touched except to compensate for vision changes over time. The "problem" with Oculars/Eyepieces is that they have a wide range of adjustment where they look sharp, as well as having very fine threads (the fine threads mean you have to turn the Ocular/Eyepiece Bell more than one might think to see any change in focus). The result being that lots of people look through the scope, quickly adjust the Ocular/Eyepiece to where the reticle looks sharp, and call it good. However, and it's a PITA so I HATE setting-up Oculars/Eyepieces, but I take the time required to fine tune the reticle focus. I never "chase my focus" and I can look through my scopes all day without eye strain.
All of the above said, as long as the Ocular/Eyepiece has been properly set, if the reticle doesn't stay in focus when the parallax is adjusted there's either a problem with the parallax adjustment, the Objective Focus, or both. Parallax adjustment and image focus are related by not the same thing. Parallax Error occurs when the reticle doesn't fall on the same plane as the target. An example of parallax is if you move your head around while looking through the scope the target will shift positions.
But as to which scopes are easiest on your eyes, my personal favorite is a (FFP) PMII 5-25X[56] 0.1 MIL DT (Double Turn) CCW Turrets. 26 MILS of UP Elevation (65 MOA of 1/4 MOA in MOA Turrets), awesome image quality & color rendition, generous eye box, 90mm eye relief, SS and brass internals for long term reliability and repeatability of adjustments, focuses down to 10 meters (33 feet) at full (25X) magnification, and 11 Position Illumination Turret. My favorite reticle is the Gen 2 XR reticle (I've shot this configuration for 15 years and now have four of this exact model PMII, but FFP means the reticle is quite small at 5X for my 60 year old eyes. IMHO, the sweet spot for the Gen 2 XR is 12X-up.
For Field Target and/or close range pest control I think some people would prefer a reticle a bit more coarse like the P4F (P4 Fine), the regular P4, or the MPR or MPR-2. One could also opt for one of the SFP versions, but there are fewer options (P3L, P4L, or P4L2-MOA). The problem with ALL SFP scopes is that ranging and holdovers are only accurate at maximum (25X).
