Drizzle vs Non-Drizzle (PixInsight)
The Drizzle files are approximately 3X larger than the non-Drizzle files. StarXTerminator took about 25 minutes to remove stars on a drizzled image and just over 5 min on a non-drizzled image. Just FYI.
Hope this is useful.

Re: Drizzle vs Non-Drizzle (PixInsight)
I had tried drizzle before, but at that time, the extra work, time, and disk space wasn't worth it to me. After using Drizzle in the new WBPP, I found it to work beautifully without much fuss. Of course, the processing time is longer and the file size is larger, but the beautiful stars are definitely worth it!
I did, however, get better star cores by taking the registered lights from WBPP and Running them through the Image Integration and Drizzle Integration processes separately from WBPP. No big deal!
You are definitely right about the longer processing times for StarXTerminator. I started using the new AI 11, but switched to the AI 11 Lite version. It still takes quite a while!

I haven't had to drizzle as I am typically oversampled with 1.2 arcsec image scale and seeing at 2.0 arcsec at its best. I tried some small targets (like M1) a few years back with
