Coding styles vary between groups and it isn't a one size fits all type of thing. The most important thing is having a standard that's followed consistently and not going overboard. Too many rules can be just as bad as not enough.
I used to prefer the K&R style (the second one). After having to adjust to the Allman style (your preference), I now feel that it makes code more readable and have changed my preference.
This Wikipedia article is a decent place to start. It also includes a link to the PEAR Coding Standards, among others.
