many years ago I did a run of Astrodon filters (and some others as well) on spectrometer to see if I spent my $$$ in a useful way or not (some stuff is still on my blog). What I learned? Astrodon filters, narrow band, though very expensive are the best quality ever! (only come always dirty in the package which is what you'd not expect from a top-brand filters, I got many of them of various sizes and it was always this way).
I can tell you one thing - for narrow band, Astrodon's are best (second in my opinion Baader). For broad band - it depends (for some large format KAI KAF series 16803 of cameras on big CDKs or Newtonians Astrodon TruBalance are the way to go, BUT for all the rest LRGB from Baader are just as OK as it can be - because for refractors - that are never apochromatic - using a highly transmitting L or B filters from Astrodon produces larger stars - and the TruBalance 1:1:1 from Astrodon is hard to match with any other CCD or CMOS chip in the camera other than famous Kodak/TSI/OnSemi KA* series - MOREOVER Astrodon's LRGB are somehow optimized for light pollution supression and I nowadays (for deep LRGB shots under a good low LP skies) prefer higher transmittance of full color spectra rather than having subtle LP filter in place - I can always add an IDAS light pollution suppression P2 filter to the optical train if I need to).
last comment: price point!!!
- cheap filters won't be the best performing ones (may only get to some close to good ones with some compromise but attractive due to low price or difference between premium filters and cheap ones)
- expensive filters are not guaranteed to be best performing ones (maybe they are maybe they are not - but there is some chance that they would be)
it's up to everyone to decide which link of their imaging setup will be the weak one (compromise).
