Baader is, in general, a good product. I had a full set of 36mm LRBGSHO (before the latest version) and they worked fine. Yes, there were halos on brighter stars (strongest in the B and OIII), but you can minimize these in post-processing.
I bought the OIII CMOS-optimized in the fall, and it worked very well. No halos. However, a number of people were reporting halos, even with the CMOS-optimized ones.
Since the price was now higher, and much closer to the price of Chroma or Astrodon, I replaced the rest of filters with Astrodons. Not too many people complain about the quality of these.
Ultimately, there is a chance you will get a filter that does not meet specs. A higher chance when you go with more mass produced, like Baader, Astronomiks, ZWO, etc..
It all comes down to how much to you want to play around with your images in post-processing and how much money you have to spend (and what you want to spend it on).
