Indeed. If you are using Psyco for example, string concatenation is converted into a list join whereever possible.

So in that case, the two are fairly equivalent.

Nonetheless, I often find building up a string in a list and then joining it to be better both conceptually and in terms of readability. String concatenation can start to look messy very quickly ...
