If you have a 32mm Bino, then don't bother with any of the 25mm options. They are too close to justify both (for me).
I have 8x32's, and I did own Swaro CL8x25's, but in reality, the Swaro's, and definately the Zeiss VP's, are a touch big for a really pocket friendly bino.
I sold my 8x25's and have gone (back) to 8x20 Ultravids, having been swayed by the larger everything on 8x25's!!!! Ultravid 8x20's are significantly smaller, and DO go in a pocket, or un-noticed around your neck.
If you want small, then buy small, and don't go half baked on it. Sure they are more fiddly, less bright.... but the image is superb, and plenty bright enough in daytime.
I use my 8x20's way more than I did my 8x25's, they are always with me, and I've got used to the tricky handling already..... even with spade sized hands!!
But before anyone jumps in on ergonomics, exit pupil, fiddly dual hinges etc..... YEP..... but that is the compromise of pocket bins. No getting around it.
I will always use my 8x32's primarily, but those little 8x20's do their job superbly.

25's are just too middle ground, unless you can only have 1 binocular, in which case I would definately recommend 25's over 20's. But even then, you may as well stretch to single hinge 30'/32's..... there's just not that much in it.
Well, that's my thoughts from someone who has been through it too
