For me even tho he has six losses it is definitely rich "ace" Franklin, lyoto machida, Anderson silva x2, Dan Henderson, vitor belfort, and forrest griffen, all world champs. Thoughts? 
Rich is definitely up there.
He isnt the most talented fighter of all time, but he has tons of class and respect and has only lost to the top tier guys in the sport, and beaten quite a few of them himself.
Hendo's is really good
Wand
Arona
Lil Nog
Big Nog
Misaki
Rampage
Anderson
Shields
No TKO losses

Yeah, thats a big sticking point for Hendo.
BacktoSamsClub - Bisping, he's never been ko'd. Oh wait...
Bisping's one loss is worse than all of Hendo's combined.
Fitch's 1 loss to GSP in the last decade only strengthened his image as a fighter. His 2 stoppages early in his career are so distant they don't matter much today.
Yuji Nagata
0-2-0
Fights Fedor and Cro Cop, when they were the two most feared fighters in the world.
Honourable mention to all the Japanese punchbags that Pride brought in for the most savage animals on their books.

I think Rich wouldve been better off against Andy if hed started on a knee. You know, so he couldnt get kicked/kneed in the face........
j/k...i love rich.
The fitch mention makes a lot of sense. sumabitch is a tough fight for anyone
Yeah if your going by the way they lost then hendo would beat rich, because rich was brutally finished a few times. But going just by who they were it's ace. And yeah that pride dude who got set up with Cro cop and Fedor Lol.

Bisping lost to Hendo and Wand. I also think Hamill was robbed and Bisping ran for three rounds from Leben.
...add Sherk and Tito to that list
MoSubsMoProblems - I would have said Aoki pre-Nagashima.
Instead I will say Edgar and Melendez.
The Nagashima loss technically didn't count :P
Hendo's is impressive but he has a string of questionable decisions in Pride. He was called decision Dan for a reason back in the day.
Machida
Hendo was the first one to come into mind.
Jon jones only loss was pretty impressive.
