I use Vallejo acrylics and for me the gloss and satin don't work too well - they never seem to have any shine to them at all. The matt, as others have said, are very matt, although I do find it peels off quite easily when handling. I'll need to find another brand I think.
Alex - do you make sure it cures properly for 24 hours before handling?
I use it all the time and do not find it a problem. I always leave 24 hours between coats of paint and varnish and most certainly before applying masking tape.
