Where do you rate Wladimir Klitschko among all-time heavyweights?

[Freedom]

For what he's accomplished so far in his career, where do you rate Wladimir Klitschko among the all-time heavyweights?

He's beaten a lot of very good fighters (Byrd X2, Haye, Ibragimov, Chagaev, etc.) but never a really great one.

But let's not forget, there are other heavyweights generally ranked among the all-time greats who don't have a prime, ATG HW on their resumes.

Wlad has taken many "0"s and stopped many durable opponents who had never been stopped before (Chambers, Chagaev, Thompson, Brock, Barrett, Castillo, Brewster, Shufford, Shultz, etc.).
