Short answer is, in this case, mostly no. Beveling would add additional detail for the UV Map and texturing, but it wouldn’t necessarily make the edge sharper looking. Also with that angle you would probably have to play with the bevel’s profile to get the proper look. This is of course looking at it from a game development aspect. For 3D VFX and animation then beveling would most likely be the preferred method.
Mark Sharp has a few things that it can be used for that bevel can’t. There are modifiers that use it to reduce or ignore those edges for processing. It also affect shade smooth normal calculation and the newer geonode modifier(auto smooth/shade by angle) doesn’t export to most outside texturing tools or game engines.
You will find that when it comes to 3D there is a lot of it depends. To use the CG Cookies mindset the answer would be try it out. Play with both. See how they differ and make lots of mistakes. As Wayne says, “Making mistakes means you’re learning.” I’m paraphrasing but the lesson is still the same.
