Some great person once gave this advice to me on US TDs -
US TD lines are quite unique because their Tier VIs are both turreted with differing characteristics.
Hellcats have been praised and respected because it has mobility, good gun depression with decent mantlet and a nasty 90mm gun with decent DPM and gun handling. However, it has tissue paper for armor and rarely if ever survives if pushed into a 1v1 brawl with most tanks in its spread apart from casemate TDs, and even then some of those can just delete you from the match with their HE rounds (SU/ISU-152s for example). Therefore this tank encourages you to be a shoot and scoot player; go after distracted targets from the side and rear, unload several 200 average alpha shots, and then either move in and secure the kill or move away once you see their guns turning towards you and repeat the process from a different angle.
Jackson trades the mobility for better armor. While not up to scratch for medium tank standards, at least you will be a difficult tank to one-shot with HE, and mobility wise it`s not that bad either. With some pre-planning you can reposition quickly enough to make a difference, and the armor allows you to play ersatz medium tank with 90mm gun in a pinch; DO NOT however, make that a habit as the poor side armor and slow turret rotation time can get you killed in a brawl against real medium tanks. Even so, I do think it still makes a nice pairing with mediums in a wolfpack, sniping any targets they spotted from a second-line position where you`re not too far away to get in there and provide direct support and share HP pool if needed, or pair up with heavies and provide flank protection.
Another advantage to the turreted TDs is that they can move their turrets only and track targets without having to lose and reset camo, thus delaying detection by the red team.
