nope, not all paints are the same.
For brush painting, Ive heard that Vallejo is one of the best. I use ModelMaster enamels in those little 4oz jars and have no complaints. Other company's enamels are good for painting too. Some even use oil paints on figures. I would stay away from brush painting Tamiya acrylics though. That brand does not like paintbrushes for some reason. Generally, enamels cover better than acrylics. I find that acrylics are a bit thin for hand brushing...maybe Im just using the wrong brand!
