I would have to say Xray 008 or 009.
I was a AE fan boy for years, but not anymore. The best design features and ease of wrenching are far worth the extra you pay. Xray diffs are superior and I've never broken a thing on my 008. Unfortunately Xray has priced me out of another future graphite kit, so if available, my next kit will be fiber glass. I won't pay over $400 for a TC anymore, but I will say I love my 008. I would go with the T2R in my opinion.
