They're only alright in group fights, and their 1v1 advantage can be neutralised by Not Jousting like a lemming
It's not that hard. Stop fighting every ship like you're in a VHF fighting another VHF. I can kill superheavies pretty easily by staying behind them, CD'ing their mines, not getting in front of the nose where all the cannons/guns/missiles/razors are. This is easier to do because they are heavy, heavy superheavies with bad turning circles.
This is a problem with Conn 1v1s in that it encourages jousty-strafey play. Superheavies are the hard counter to that. It's not the only way to fighter PVP.
That armour doesn't last as long as you might think either, since the Super Heavy's primary defence is that armour, not relying on avoiding every projectile.
