To drizzle or not to drizzle, that is the question ...

I've reading up on 'drizzle' processing of deep sky images. From the examples I've seen on the web, it appears that drizzling brings about tighter stars and sharper detail, but at the expense of increasing noise. What is your experience?

my very limited experiance of drizzle has so far been positive, yes there is an increase in noise but the gain in detail is worth a little extra noise for me personally

attached is zoomed in section of the north america neb on left a normal stack and on the right a drizzle stack (both images have had the same stretch applied)

i will say on the different images i have tested it on narrowband data seems to benefit more than LRGB but that could be to do with my data
