Which 4th gen...
I know there's not much differences other than HP and Torque levels, but, I am wondering more about power delivery on the autocross course. And, yeah, I know 99+ have the best rear ends for AX. Maybe Sammy can weigh in on this subject?
The last time an f-body won FS at Nationals was in 05, and it was an LS1 car driven by Aggie Casey Weiss. The 3rd gen 1LE's, LT1's, and LS1's all have their advantages. 3rd gen is lighter, but has less power and has the lowest red line. The LT1 has the most low end torque, but again runs out of steam on the top end. The LS1 by far has the most power on the top end. At various National Tours this year, both an 3rd gen and LS1 have won, even beating the new Shelby GT twice (NOT the GT500).
Also, while getting a 1LE 3rd gen is important, the 4th gen 1LE's aren't that great. It has been proven time and again that a well driven base car is just as fast as a 1LE.
However, these differences are not that great. Any car that is very well driven can win. Driver and tires make by far the biggest difference.

I will take for granted you are implying a base car with Koni adjustables (at least SAs) and NOT one with the stock De Crapons. This is, of course, given drivers of at least close skill levels (as well as equal tires), since if the disparity is great enough there, the handicap of the OEM shocks could be wiped out.
