I suggest sticking with 8X and 40(ish) mm objectives for your price range. Fact is when you increase the power the more noticable the inperfections in the glass/coatings or image. Larger then 43 mm objectives are harder to hold steady, they are also bulky and simply aren't needed for hunting/carry bins IMO.
As too which one let your eyes do the talking. Just make sure to view outside the store lights. I also suggest comparing under both good and fading light. it may take a few trips but its worth the time then being disaapointed in the field.
