Whereas I think that's confusing: The { is just visual noise, and I'd rather it were out of the way by putting it on the line above. That way I can focus on actual pattern: It starts at the sub/if/loop, and ends at the brace. (To me.)

But it's all personal opinion. The one thing not to do is to mix styles. If you use one in a particular source file/project, use it throughout. That way people know what to expect when they read/skim the code.
