What are you using them For?
If you are sitting on top of hills glassing for game.. Well that is differnt than a pair that you are planning on mostly hunting predators..
I have 8 power Vortex and love them.. Very clearn and i scan around every stand before i sand up. I choose 8's because it had a better field of view than the 10's IMO, and I can see coyotes over a mile just fine with them. I am looking for 500yrds or less and in the shadows to see if there is a bobcat sitting and watching me.
I can spot ELk way off without an issue, and don't need bino's for that.
So it comes back to what you are going to do, and how big do you need for your purpose. I went with the smaller, lighter ones that i will wear all day.
but Vortex over anything else.
