I just bought an angled one and I find it takes a bit more getting use to but seems to work the same.
I've owned both and I prefer the straight.

Id use straight over angled any day. Lots of times you only have a few seconds to look something over before it disappears behind brush, id hate to miss out on something if i was messing around with an angled scope...
