It's pure preference. If you don't like it, you should definitely not drink it, there are a million types of beer out there and you shouldn't waste time on beers you dislike.
I like IPAs or PAs for several reasons
-I find porters/stouts/bocks a touch too much on the "mmm this is like chocolate beer!" side.
-I think slightly bitter, crisp beers go better with food, especially pub food
-I like high alcohol content, IPAs with high ABV are pretty common
-IPAs are also interesting enough to drink completely on their own, which I can't really say for something like a lager. Unless it is bloody hot weather.
Here's a real life example. My costco gets some pretty good quality beers in boxes. I have tried the Sam Adams variety pack, the Biersch variety pack, the Mendocino pack, the Spatens, the rogues, etc. I always find myself going back to the Sierra Nevada Pale Ale which they always have in stock.
