So far, I have used the following (3) recipes on butts:
1. Mr. Brown
2. Chris Lilly's
3. Alton Brown (brined with salt & molasses)
Mr. Brown was a bit "too peppery" for some guests tastes, but some people liked it a lot.
The Chris Lilly recipe is consistently a hit. The bark that you get on this one is a combination of crusty / savory / sweet. If you want to "heat it up" - you can always add some pepper-head-oriented sauce on a sandwich.
The Alton Brown recipe was also good, but I've only done it once.
Sometime, if you're cooking for a largish group - try both at once, and see what you and your guests prefer.
If you like to make pulled pork somewhat frequently, it's good to be able to use different twists from time-to-time.
Hope this helps
