After trying Vortex, I find Super Nova Balanced still better. I don't doubt Vortex shows better results in TFF's tests, but in my current save Super Nova is far, far better.
Maybe it'll change, who knows. Super Nova is a flat 4141, which gives you two banks of four to defend. It's solid, and when you get the ball, your midfield surges forward to help the F9. It's great to watch.
In Tornado and Vortex, you have two IFs which don't do enough defending, even on support. It's been a known issue for a long time in FM that players in AML/R stratum don't defend well enough. Apart from that, you have wingbacks, one of them even more advanced so it's a whole lot riskier. Fullbacks, even on attack, are not as reckless.
I don't doubt Vortex is amazing for some people, but for those who struggle with it, I recommend sticking with Super Nova.
