I like acid, but it's a workout. I treat it like a lucid dream-- the first time I didn't really understand what was happening, but every time after that it has been easy to separate the trip from reality while still appreciating the trip. I wouldn't ever go out in public while tripping, and will only trip if I can hang out outside and look at the plants, the grass, the sky, and the trees in privacy. It wouldn't be good to have some straight person gawking at me while I watch the vegetation grow. Calling it "fun" seems like a misnomer. Ecstasy is fun. Acid is more like experimenting with reality. I would even call it educational.
