I've found and several posts Ive seen elsewhere seem to indicate that most paints seem to be getting worse. This may be due to the changes in chemistry forced by regulations. The two main problems I've noted are that paint is harder to lay-off so finish is poorer, which may need a change in technique, and many finishes stay "sticky" longer, by which I mean they are touch dry, but where touching, like cupboard doors or windows and frames, the paint will carry on sticking to other parts for days and days. The last paints I've used which were disappointing were F&B, Dulux, and Sadolin, the ones which seemed okay were Leyland and Sikkens. Though I'm not comparing like for like.
