Well I will get beat to death, but here goes.
I have a 2001 sport and an 03 rubicon, so I have both axles.
My 01 had a hammered 35. I'm sorry but the axle was junk. Did not want another tooth pick, I shoped for a 44, couldn't find one. Studied the 8.8 and became impressed. It is stronger by quite a bit. The big one for me was also the cost, it was $50. For that cost it has factory installed 4.11's and disc brakes. Yes, it is an inch narrower and the opinion shaft is offset. Neither has cause me problems.
I have a shop with a plasma cutter and welders so that expense was not an issue.
Granted, had it I been able to find a 44 I would have went this way probably. But not at the $1000 plus.
I was not thrilled with the super 35 stuff. The axle is still a tooth pick.
Ok guys, beat me up. I am 70, I can take it
