Macro lens for D5100

I went with Tamron 90mm that has been suggested several times in this thread also. I have been very happy with the lens even though my version doesnt have an AF-motor. So when using my D5100 its manual focusing only. Got it cheap and figured that I focus macro shots manually anyway...

Here is one comparison that suggest the Sigma 105mm f/2.8 EX DG OS HSM Macro for best quality and the 90mm Tamron for those in budget.
