That armor is okay, but not great. For us to tell you which armor would be great, you have to tell us which weapons you use. Why? Because the most important consideration in armor is the offensive bonuses that it gives you. To learn more, you might read my detailed armor guide.

Supernova, like all Pulsar-line guns, lets you inflict lots of knockback at long range. So it can be useful. But it can also annoy your teammates, and it's not especially good at inflicting damage. In handguns I would recommend the alchemer/driver, Magnus, and maybe Autogun lines.
