Overall, T-34-85 (D-5T) is way better tank compared to Sherman VC Firefly in most category. slow acceleration and top speed (41km/h) higher RNG bounce on T-34 hull when angled, need to aim at weak spot. armor of a M4 Sherman, very thin for a Tier 3 vehicle armor is useless in tier 4+ matches (BR 6.3 and up when bringing higher BR lineup) + cheap repair cost, twice quicker free repair time + crews are protected by inflammable tanks + fast and excellent maneuverability, one of the best for its tier

+ main gun wobble much less while moving than its predecessor + turret ring module itself is a small target + overall hull armor can bounce higher BR tanks quite reliably

+ 1 shot king, stock BR-365A (APHEBC) shell does respectable damage upon penetration. Really hope Gaijin will take closer look at those vehicles (BR 5.0):
