Painting in acrylics

Has anyone tried acrylic paint? My husband is a keen artist but he has always used oils, however he decided to try acrylics because they don't smell so much and I wonder if anyone has any tips?

I use acrylic paints. I find it easier to paint in layers. I usually wait a bit for it to dry, because the acrylic seems to blend in harshly with other acrylics (unless I am doing something wrong). I like to start off with covering the canvas with gesso. I also like mixing in textures with the paint. :)

Thanks brooke. That's helpful. He has mentioned already how quickly they dry, how easy it is to get good textures and how bright the colours are.
