I agree with Barney here with one reminder: remember that you can put functions inside custom tags. Not many people seem to remember that. I've found that most recursive tags could be remodeled quite easily with internal recursive functions. A function in a tag is contained within it - there's no exposure to the rest of the template or really any downside that I can see. I've done no testing to back up the claim but I would say that recursive functions would be much faster/less-resource-intensive that tags. Tags maintain a lot of references (the caller chain, the tag nesting chain, etc) not maintained by functions and so forth.
