Can't do accurate weight painting with Blender I learned with Maya, mastered it, I am a pro. With Blender I am less than zero, a complete incompetent. The most challenging for weight painting is the butt. Default weights make the butt look like a fold when sitting so it needs fixing so that the volume of the butt doesn't shrink when the legs are bent and you don't want the torso to indent either. My solution, I have to export just to weight paint so I can use a smoothing brush and also, so I can contour an inner thigh without the brush hitting anything else. 

It takes finesse and the correct tools and accurate tools as well. Selecting only affected mesh points and using the smooth function and I still can't get results. I feel like I'm using a keyboard as piano keys sure you can make music but it feels clunky and lacking.   

But I must be doing something wrong as I seem to be the only one who feel like a complete incompetent that I'm willing to pay just for better weight painting tools. Maybe a plugin I could buy? Hiring someone to make a script? Anything?

At least is there a tutorial that would show me how to master weight painting in Blender? I never found any tutorials that addressed the skill of weight painting with Blender. Sure there are tutorials on the basics but never showing advance skills.
The solution is Blender v2.78 

Weight Paint bug fix for v2.78: Blur now smooths between connected weights

Previously it would average all the points under the brush and applying that value, giving an off a feedback loop that often depended on the direction of the brush stroke, giving a not-very-useful smearing effect. Now blend brush smooths between connected edges as it should.

Now there is a real smooth brush that was greatly needed. Now I can do all the weight painting in Blender, also I discovered Alt+B to make a square slice to isolate part of a shape to have an unobstructed view of where you need to edit.
