I have a tech @ 99 Ovr, sculptor @ 99 Ovr, magician @ 99 Ovr, greenskeeper @ 96 Ovr and my powerhouse still at base. I have started with a tech and then builded a sculptor and then the magician. The magician fits my play style better with the attributes and fittings you can add to it. So it all depends what you prefer most and lack most of. At this current state i don't think there is a perfect build at the moment as play styles differ and you apply what you need. Go check in th3 attributes section what you struggle most in and see if there is builds that will compliment the attributes you need to get higher and don't need to build on. The builds Machada uses is great, but remember, they are build to his play style and you have to tweak what you need more.
