Personally, I'd stick with the MBIL discs if they're doing the job. Chances are, it'll say Made in India on any brand's packaging, so they're easier to pick out than say CMC or Ritek.
Most of the brands you mention, use lots of different manufacturers for their discs...what I tend to do, if use something like Taiyo Yuden for my "master set" of CDRs, then something like Moser Baer, CMC, Sony or Ritek as a backup.
I'd stay clear of Intenso or AOne branded discs altogether, but you could pick any one of those other brands as an alternative, really. Entirely up to you.
