What kind of strings do you prefer on your guitar?  

I use Super Slinky's but then again I haven't exactly tried 30 different brands. I play acoustic and they work just fine for me. I think for advice about a specific guitar string it's good to ask a knowledgeable person at a guitar store that is familiar with your type of guitar and the style you play the most.

I usually use ernie balls, except for my warlock NJ speedloader, those need special strings from fender.

I do use fat earnie ball strings. as you said they last long, so strong that I forget to change them.

I like ernie ball 'slinky top heavy bottom' for my electrics and elixirs for my acoustics. GHS Boomers are good, I think all around not just for metal.

I use Elixir guitar strings for my Gibson Hummingbird. They are polyweb and repell dirt and grime between the winds in your strings which deaden the sound. I like them better than the Gibson factory strings which came on the guitar and Gibson strings aren't cheap. I also use the custom lights so it is easier to bend notes with a bass sound that still rings out.

well i prefer some soft american strings,because they sound to much better,and also get bend easily,but not that much soft,semi soft u can say,because sounding is too good and,but if u wanna do metal so you have to buy hard one,that will be more good for metal rock and all!

yeah, ghs boomers rock. I also like d'adarrios (sp?)

Ernie Ball's really a tough one, but expensive to!;) I know use ROTOSOUND strings, it's quite durable and very flexible. If you want to know more about it, try to look for their website. I won't post it here for the sake of the discussion!;)

I use D'Addario Extra-Light Phosphor Bronze strings for my acoustic guitar & Ernie Balls for my Electric.

I prefer elixir strings for my bass. If you can afford them, you should try their guitar strings.

They have a coating on them which extends their life. The set on my bass have been on it for 7 years. The coating has worn off but they are still great.
