Whew. Sorry for the long post.
My opinion:
I prefer a turbo charger. There are more options on the market. They are more configurable once in place. Turbo lag can be minimized and there is more high-end gain.
Both types of systems really take the same amount of tuning and maintenance. Yes, a turbocharger is more difficult to install and costs more consequently. But, a turbo properly matched to your driving needs (drag, auto-x, rally, etc) can really be a lot of fun.
