HTML is easier, but PHP is better. If you just want a simple website without too much that could go wrong, then HTML is the simpler option. If you want a dynamic website that allows for near limitless customization, including but not limited to visitor participation, then you want PHP, but it's harder to get the hang of, and things can go pretty damn wrong if you don't code it right.
At least, that's how I've always figured it.
Also, "awkward."
