I started with a Spigen Neo Hybrid and a WSD screen protector. The sharp corners on the Neo Hybrid drove me nuts. Added a skin and switched to the S View cover. Loved the S View, but it wasn't really practical with my car mount...
Today I removed the WSD because it was really making note taking with the S pen terrible. Removing it makes the FPS so much faster, I don't think I'll miss it. I really like how smooth all of the edges feel with no screen protector.
So, long story short, mine isn't quite naked since I have a skin on it, but it's as close as you can get; And if I find myself in a situation where I want a case, I can throw the S View on over the skin.
