Best BD Media Manufacturers/Brands?

Which manufacturers/brands make the best BD media these days? (Sony, Verbatim, TY?) I did a search here using relevant key words but only got hits for standard and DL media…

Currently it’s not that easy yet. A this moment drive and media seem to fluctuate, but also media performance is quite drive dependant.
I suggest keeping an eye on the japanese sites, and legendary German computer magazine c’t (or cdrlabs forum for summaries of c’t )
