I mean to be fair it is pretty hard to determine which plane is better , If we are talking about the weaponary the A-10 is just superior having a weapon load of more than double of what the Su-25 is able to carry , and also by having a unnecessarily big gun that does ( to an extent ) negatively affect the plane due to the massive recoil it producess . However if we are talking about the planes speed agility and maneuverability , the Su-25 takes the cake as it is both smaller faster and more nimble . And point i would like to mention , which i think is the most important part of this debate , Friendly fire , The A-10 is notorious for having a huge amount of friendly fire/friendly kills ( accidental ofc ) and i am quoting this from the Air Force Times " The Air Force A-10 attack jet has killed more US troops in friendly fire incidents and more Afghan civilians than any other aircraft flown by the US military. " ( i obviously know that some information is not 100% true but this was the best i could find ) altough there was a su 25 shot down by friendly forces and there were minor friendly fire incidents from the plane , however still much more less than what the A-10 did . And the last point , How many of each were shot down , there were rumors of Ukraine troops shooting down 7 Su-25's with there only being the evidience for the 2 of them , and suprisingly A-10 having the same amount of aircraft shot down ( 7 ) . And dont get me wrong , i like the A-10 as much as the next guy but anybody can say any plane is better and thats their opinion that can be argued with , if anything i made this edit because i like the Su-25 more personally . Also if i have made a wrong point anywhere in the comment feel free to correct me , i am not a professional in the air industry or whatever , i just like planes in general . Have a blessed day brother .
