I'm partial to angled scopes for range use or almost anywhere else, as they allow the tripod to be kept at a lower level and thus improve steadiness. I also think that they're a lot more comfortable for range use, making it a lot easier to shoot, then lean over and take a peek. They do, however, take a bit of getting used to before you are able to quickly find an object in the scope.
For hunting, on the other hand, I think you're better off with the straight model. Most hunting scopes are on the smaller side (50 or 60mm objectives) and many of these don't come in an angled version, so going with the straight configuration gives you more options to choose from. They will allow you to keep a lower profile, say at the top of a hill or over a rock or other piece of cover, exposing less of your head to be spotted by a hopefully-soon-to-be-defunct critter. And a lot of them have a set of rudimentary open sights on top to make it easier to aim them at a small distant target. This last feature means very little if you're the only guy using the scope and are familiar with it, but it helps if you share it with someone else.
My $0.02.
