مدى صواريخ التي 90 س اكبر من مدى الابرامز من 1 كم الى 4 كم يعني التي 90 تملك نسبة اكبر في الاصابة حتى قبل ان تدخل مجال اطلاق الابرامز
كدلك قطر مدفع التي 90 س هو 125 ملم في حين قطر مدفع الابرامز هو 120 ملم
مدى السير للتي 90 س هو 550 كم في حين مدى السير للابرامز 465 كم
نظام شتورا والدروع التفاعلية تعطي تي 90 افضلية في البقاء
