Depends on what your using it for or rather what gameplay you prefer, i don’t have much experience on the ISU-152 as i am not a fan of tank destroyers so i have always used the T-34. Isu is a tank destroyer so its good for sniping and just laid back game play, i do not reccomend playing offensively as they can shoot your tracks out, take your barrel and proceed to flank, but it reall all depends on what you’d rather go for or play
