I've also tried d4. I didn't like it quite as much as e4.
As for anti-Sicilians, I've tried them all and like the Alapin best. It's a great opening, and there are some really informative posts above about it. I was so happy when I found the Alapin, or more specifically when I finally gave it a chance and realized how much I liked it.
Used to play 1. d4 when I was in my teens, but I could not stand the slav or any defense where Black prevents e4. I love a pawn at e4, and if possible e5! The anti-sicilians seem to be the best way to atain that goal.
