Straight for me. A lot easier switching between binoculars and spotting scope with a straight. Angled definitely has a few advantages though.

What are they? I have no experience with spotters but I’m interested in getting one as well
Pretty much just what was mentioned above, IME. If looking at a steep uphill angle, a straight spotter requires you to get lower to see through it. Additionally, if shooting from prone or off a bench, a straight spotter requires you to get off the rifle and move more to look through the scope. Some people prefer angled for truck-mounted use, but I'm not one of them unless looking steeply uphill.
