Depends what kind of painting you want to do. Wicked is a great all round paint that is good for virtually any surface, incuding fabrics, leather, automotive etc. I use Wicked, and until recently only had an eclipse HP-CS, and I love the flow. Having said that, you do need the brand reducer (it doesn't reduce with water), but apart from thinning the paint, it does have other properties that make it well worth using. It is a paint that you have to get to know a bit (I guess that is the same with many paint brands, but some people don't get on too well), I find I can use it through my Custom micron just fine. If you are only going to be doing fine art, then a more specific paint like Com-art, Createx illustration or E'tac may suit better, and as mentioned, Com art works well with water.
