I've tried a few electric razors over the years, and I've never liked them.. they've always done a poor job comparatively and my face is always irritated after using one. Right now, I'm using the Gillette Fusion, and it's probably the best safety razor on the market... smooth shave with no razor burn or nicks.
But if you know what you are doing and have the time... there's nothing like a straight razor shave.
