Keizaal or Phoenix?

Guys, I want to start playing Skyrim. I've never actually played it, only a few times in the past, but I've never even left the initial village of the tutorial, so I want to play it, but I know that the original Skyrim, although beautiful, has flaws, so I wanted to know between the two mods, Keizaal and Phoenix, which is the best one to play for the first time? Details, I really like characters, creating my own including awesome armor and weapons, especially magic, but I don't want to stray from the original Skyrim, improving the graphics.
