People talk about Machida but he pretty much got beat by Shogun, or at least taken to a razor thin decision. I don't recall GSP, BJ or Anderson being in any close fights at their weight class in recent times.
BJ has completely destroyed Stevenson, Sherk, Florian and now Sanchez. Machida has soundly beat Ortiz, T.Silva, Evans and got a close decision over Shogun that many feel he lost. It's not really comparable to the absolute destructions of Penn, who convincingly finished all of the LWs I mentioned. I don't think Machida is even relevant in P4P at the moment.
P4P best is a difficult topic. Fedor has beaten more fighters that are heavier than he is, but GSP, Silva and Penn have beaten the current best in their divisions. From what I can remember Penn has done this more convincingly than anyone else. He hasn't been rocked or troubled by anyone at LW in a long time.
