I own both, and prefer the strait eyepiece. Why? I wear glasses, and tend to get a better focus. But I also used the the angled one for years with out a hitch

i use an angled for pistol shooting or sitting while i'm spotting for someone but when i'm shooting my rifle from the prone position i use a straight just because thats what i'm most comfortable using
I would say angled, as at the bench I can spot for myself. In the field I must admit I have not ever used a spotting scope, just my Leupold Binoculars.
I have only had one angled spoting scope and it was one of the original heavy, boxy
Swaro. All my other spotting scopes, of which there have been B&L, Bushnell, Leupold Gold Ring 12x40-60, have been straight. Old habits are hard to break.
My spotting scope is straight. Why? Because that's what was on sale at the time. I know that's the worst reason but it worked for me at the time. Sportsman's Warehouse was closing their Vegas Valley stores and the spotter I bought I got for 40% off their regular price. BTW it's a Nikon20X60X80.

I prefer the straight spotting scopes simply for the fact that i use it 75% of the time for hunting and vegetation usually forces me to set up the scope high enough where an angled scope might not be as comfortable for my needs.
