I started off with Baader 2" LRGB filters but switched to Antlia Pro V LRGB 2" filters, which I am much happier with.  The stars are much easier to control in processing with the Antlias.  

I also have the 3nm Ha and OIII from Antlia and am likewise very pleased with them.

I have LRGB filters from ZWO (31mm size) I don't see reasons to complain. No haloes, and parafocal enough that I don't need to refocus even at f/4 with a tight sampling (0.66"/pix).

I don't have a full SHO set but I had a Baader 7nm H-alpha which produced big haloes. I replaced it with an Antlia Edge 4.5mm which is much better.

I have two set-ups (SkyWatcher Esprit 80ED and 150ED), both with ZWO 36mm unmounted LRGB+NB sets (manufactured 2020 and 2023) in front of ZWO ASI1600MM Pro Cool.

NGC281 in narrow-band, Esprit 150ED:

 

NGC7822 in narrow-band, Esprit 80ED:

 

M37 in LRGB Esprit, 150ED:

 

NGC884+NGC869 in LRGB, Esprit 80ED:

I have no reasons to complain. 🙂

Only the ZWO filters manufactured prior to June 2018 have terrible reflections in H-alpha and S-ii, see second image in this post (open in Chrome for a translation).
