Conclusion
M18 Hellcat
For an extra 7 points you get a faster vehicle. A vehicle that can shoot and scoot and also be used for triple moves with only a small chance of it breaking down.
StuG III
Slower, but more capable of taking the fight to the enemy, the StuG III can be pushed forwards to support the infantry, Panzer IVs and Panthers. It can take more fire than the M18, but has to stay in the fight.
Which is Best?
The M18 is more expensive than the StuG III, but only marginally so. It all depends on how you use them tactically. Push your M18 platoon forward and it’s much likely to be Dispersed than a StuG III one. Deploy it as a hidden unit or in a Blind and it can hit and run, then use its fast speed and good reliability to harass the German Battle Group’s flanks.
The StuG III is cheaper and is a good hard hitting tank destroyer. It can advance and take fire with a good chance of surviving which makes it superior to the M18 in an attacking role.
As a German player you have a wide variety of tank destroyers to choose from.
Jadgpanzer IV L43/L48
The Jadgpanzer IV L43/L48 is almost identical to the StuG III. It has the same gun and Reaction Dice, but has the shoot and scoot ability. It costs 110 points (11 more than the StuG III), but like the StuG III it has average speed and reliability. More expensive than an M18, it may or may not be better. It all depends on how you intend to use it.
