Me too, my cabinet is full of many brands and types. Before my last cleanup and disposal of old bottles, the count was about 135. Still have over 90, some used much more often, but no clear cut front runner among manufacturers.
Tamiya acrylics are my most used, but MM enamel, Vallejo Air and MM acrylics find their way onto some of my builds, they all seem to have their own strengths and weak points. I do wish I could narrow it down to one brand.
