What i've found - and this pertains to this discussion - is that each binocular requires its own approach to placement; eyecups fully or partially extended, fully retracted, jammed against the eyes or rested on the eyebrows, or just 'hovered' in front of the eyes.
The Pocket almost seems to live in its own section of the binocular world. While undoubtedly a compact, it doesn't behave like one in any way, other than losing a little light at the extremes of the day. I use it as much with the eyecups retracted as extended (not so easy in the plane above horizontal however) and use it about as much as i do my FL 8x32mm.
Moving from one to the other however requires adaption time. Once this is done, i am reminded of why i would never, never, never sell the FL. While there is that off-axis astigmatism, this is something that has never impacted on anything i've ever used them for, and has to be 'found' to be noticed. Those fat barrels, that solidity giving compactness but resistance to windy conditions, that accessible and perfect focus wheel and just the overall reliability...
I can induce CA a little more easily in the Pocket than the FL, and the FL's fabled robustness means it remains the go-to when the terrain is unknown or the circumstances unpredictable.
The Pocket though remains a phenomenal device, probably peerless in the size category. I honestly believe that - if i didn't own bins i really can't part with - i could cope with just owning this and not feel i was losing much.
I've now used it in a Portuguese Indian summer, and East Anglian winter, used it on estuaries, heaths, mountains, woodland and even sea-watching and have yet to be let down by it once.
It i could swear to its durability in a range of tougher conditions (including hand stability in high winds) it would be the perfect 10. So there!
