If you delete the .evtx files are deleted, event viewer won't work for one thing. There is no telling what else might happen, and I'm not fool enough to try.
If you delete the .event files, then you can't see them in event viewer. I delete them along with other files that can be removed with disk cleanup if I haven't experienced any already dealt with problems. It's always a good idea to look through event viewer to make sure you aren't experiencing any previously unknown problems before deleting them. Or as rich says, just don't delete them in the first place.
