I hate it when someone asks a question and someone doesn't answer it as the question was posed, but I am about to do just that. Sorry. My answer would be neither. There is much better around. Without going silly on price I would have to say Multiblitz. Not that much more expensive, but significantly better in quality. I have seen too many examples of Bowens and Elinchrom cutting corners to be happy with either, particularly the more recent stuff.
For lightweight location work I have Bron Impact lights, which have been very good. They are very simple and don't give a wide power range, but they have small. I can take six heads in two cases.
If money were no object I would go with Profoto every time, but for many of us it is.
P.S. I know I am rather late replying to this, but maybe someone will find it useful.
