OK, i say'd it was on par in terms of price to performance with the stug. It costs less so it also performs less.
Like what more do you want form a 75f vehicle
60 max range(stug has 50)
170 max range pen(stug has 180)
3.875-4.375 s Reload(stug has 4.5-5.5 s reload)
fuel difference with mediums p4 45 and p4j 65 (stug has t34 0, sherman and cromwell 20)
fuel difference with special mediums Panther 110 (stug has t34/85 40, easy8 55, sherman-76 35, comet 95)
I don't know for me they look on par in terms of bang for buck.
I suggest you use ROF instead of reload:
SU-76 5.275
STug 5.25
Penetration values are:
SU-76 Penetration near 180 Penetration mid 170 Penetration far 160 (165 at range 50)
Penetration near 200 Penetration mid 185 Penetration far 170
