I think this is a close fight. Marquardt looked good vs. Woodley at his debut at WW. But then lost to Saff....who we all may have underrated. Marquardt is still a good fighter, well-rounded.
I think Ellenbeger is a tad overrated. He is a poor man's Hendricks. His best win in his career is probably Jake Shields. Jake Shields who has looked like crap at 170 and had lost his father that week of the fight. Other than that he has beat Sanchez...Mike Pyle 3 years ago. He really doesn't have a signature win. No guys he has beat are still relevant anywhere at WW. Pyle may be a fringe top 10 guy at this point simply for his nice little win streak.
No clue who wins. I think people overrate Ellenberger though.
