Don't have higher Canon magnification experience yet, but optically, the Canon IS L 10x42 is my best 10x . It has better CA control, less ghosting, crisper edges, and equal apparent resolution to my EL SV's (the 12x50's). Noticebly better than my Leica Ultravid HD's. Zero eye fatigue. Make no mistake, it's alpha glass. It's shortcomings are size, weight, and eye cups. Bulk, strange eye cups, I'm telling ya.
I've thought about the newer 14x32 (supposedly better than the 15x50) as a complement to a nicer EL 8x or similar. But ultimately, I'm not sold on the refreshed Canon designs. They are not WP, armored, or durable feeling. I bought and returned the 8x25 because of this. Optically it was OK, with IS on it was stunning of course, even with the small exit pupil. I think that's where the 12x32 and 14x32 will win fans is that narrow FOV and that exit pupil problem is less noticeable when you can walk into a stablized view.
Generally speaking, if Canon ever updates the L 10x42, I will be the first one to buy the new version. I'm still thinking on the others. Probably won't switch to the newer 32's because of the above reasons, but I'm sure they are fine binoculars. Canon makes 10-20k optics for professional photographers that demand far more than hunters.
