Well it really depends on what your doing with it, They are the same tractor mechanically. Same motor and drive line. the real difference is position control and telescoping links. Appearance wise one is curved and the other is square. Like King said if your doing a lot of 3 point work or doing repetitive work like plowing food plots or tilling you might like position control. I have a horse farm and my tractor is more toy than tool. I chose the 7800 because I liked what it looked like in the size I was looking for. I like the whole exoskeleton thing. I do regret not getting the ATI tach all and bucket though. I will get it and modify my bucket but sure wish I did it to start with.
