One other issue not discussed yet is the MT on the CmdPanther which makes the Jackson basically a one shot vet target. To heavier tanks that it is supposed to be afraid of it has to run and cower.
While I agree the Stuart offers exceptional utility, in larger games where 2-3 panthers may push at the same location a single stuart will only be capable of annoying the Panthers. The mciro requirement is also quite high compared to the German player that can follow up with a volks blob. I want a TD that can damage the Panthers consistently. However, I do concede the point that the USF does have some snares to help the Jackson. Snares are however, only part of the larger problem with the unit.
You cant argue that in a team game the enemy pushing together vs your TD with only a Stuart to back it is so much an issue on the Jackson than poor play on your teams part. A Jackson behind an armful of t34s or a soviet mine field (or even a pair or REAL at guns is nasty, throw in a con army of at nades and you have a few dead panthers. HOWEVER the lack of durability on allied TDs is amplified by the SHIT pathing in this game and I agree that heavy crush would be a great buff that isnt really a performance change, more "relic proofing" the unit...
