I've had both & prefer the angled for prone in the dirt shooting, but not for use off a bench because you are too low on a bench to use the angled eyepiece.
Here's my setup on a bench, the scope is separate on a tripod & I have to get up to use it.
The scope is actually a small (4") astronomical scope with an inverting prism & shows .30 cal holes out to about 250 yds.
