Which do You like best and where do you get them from?
I use a massive scrim mainly, but also a Unger micro.
I havnt got the smoothest of hands and find some microfiber cloths click and irritate my hands. No problems with scrim but they don't absorb as good.
I was looking to get a large microfiber cloth and came across loads of different types. I am guessing I use Unger smooth, but not sure.
I use them on van screen all the time.
