What is the differences between the 1994-95 5.0 and the 93 and older 5.0

[Raw Power]

If the 94-95 mustang so superior then why does every knock the car so much, is it because so many people have the fox bodies that they don't want to like the sn95 body. If that is it I can understand because I used to have a third generation Camaro and I think that the fourth generation camaro is so ulgy and that is why i'am looking for a mustang, so if I ask alot of stupid questions, I just want to know what is the best mustang to buy with a 5.0L.
