Upgrading narrowband filters: is it worth switching from 7 mm to 3nm?

Hello all.

With galaxy season coming to a close, I've started a narrowband project for my monochrome camera. With only preliminary data, I noticed a severe problem with my ZWO OIII 7 mm filter. It seems to produce terrible halos around bright stars (I’ve included the images below) and this is apparently a very common problem with this filter. I've upgraded to the Antlia OIII 3 nm filter and I'm waiting for it to arrive.

I wanted to ask experienced people in the community, do you think it's worth it to upgrade my other Ha and SII 7 nm narrowband filters while I'm at it? Those filters don't seem to produce artifacts but I'm mainly asking with regards to the benefit of going to a smaller bandpass.

Thanks very much for your input!
