Armorpaint might be what you are looking for. Blender texture painting is nice, but Armorpaint is much closer to the substance painter experience.
Edit: For example, with Blender texture painting, unless you're familiar with nodes, you would usually only set up one texture at a time.
Armorpaint also uses nodes, but it also uses a layer system just like substance painter. You can then modify the texture using nodes if you want to.
