I tried three different integrations in PixInsight - normal, Bayer Drizzle (1x with 1.0 drop size) and Drizzle 2x with 0.9 drop size. The Bayer drizzle did a better job on the colour as you'd expect - less bleeding of colour in/out of stars, but resolution and overall quality doesn't seem much better than standard integration. This version presented above uses the standard drizzle to produce a 2x larger image with much better resoluton. There is a noticeable difference in the size of small stars, roundness of larger stars and many more tiny stars in the galaxy arms. Even when downsampled for presentation (5x in this case) the image is much superior.
