It is all "personal taste": especially for pelagics, where you can't use a 
scope, and for the rainforest, where I prefer not to carry my scope around, I 
love my Leica 12x50 (yes: twelve by fifty). For e.g. distant Pterodroma petrels 
on pelagics or small birds in the canopy there is a great advantage over 
smaller binoculars. For me there is no major difference in shaking, which 
starts to my experience at a magnification of 15+. Moreover, modern 10x and 12x 
binoculars have a wide angle and a very light sensitive, albeit not as wide an 
angle and not as light sensitive as 8x.
The major disadvantage of my Leica 12x50 are close up views of butterflies, 
dragonflies, hummingbirds (in the Americas) and so on, where smaller bins are a 
great advantage over mine.

When I purchased new binoculars recently to compare 8 times and 10 times it 
was suggested to me that if a bird is 50m away an 8 times will bring it up 
to the equivalent of a little over 6m away while a 10 times will bring it up 
to an equivalent of 5m away. If you compare these distances of 5m. and there is not much difference in looking at a bird.After taking into 
account such things as shake, field of vision, and weight I finished up 
buying an 8.5 x 42 binoculars.
