Because Ultravids are just so nice!!!!
But there's not much in it optically, I have looked through them both.
Actually there's not much in it optically between the 32UVHD+ and my CL 8x25's.... certainly not enough for me to swap!!
Funny, I have absolutely no problem with the dioptre on the barrel, it never moves, and if it does, it's easy to spot.
But...... we all love a bit of quality, and those Leicas are just gorgeous..... I've got a real soft spot for Leica, even though I don't own any anymore..... but maybe one day...( after I've got those Habichts I keep promising myself )😀
