OP, there are all sorts of reasons to choose either profile trigger.
In most cases, I've noticed shooters need to acquaint themselves with the straight profile trigger after it's installed, especially if they don't have a similar trigger on other rifles.
Straight triggers on hunting rifles have a place, especially for shooters who do competition circuits in a serious manner, and they have straight triggers installed on their competition rifles.
Straight triggers were, at one point, an indication of an extremely light trigger pull weight, say 2 ounces or less.
This is no longer the case, as I see a lot of rifles with straight triggers in the field and on the range, installed on hunting rifles with 1.5+ lb pulls.
If you go the straight trigger route, practice will make perfect. I suggest you get or make up a snap cap for the rifle you want to install it on, so you can become comfortable with the profile, before taking it to the range or hunting.
Once you're comfortable with the feel, there really isn't much difference, unless your stock profile is already too long or too short.
