I have used all three, I have Avons Venom AM42 now, they are ok they have a unstable feeling riding over asphalt patches or grooves on the road. After these ware out I'm going back to Metzlers,only one size bigger. I did get good mileage on the MEZT. 8grand (little over 1/2 wear)when I switched to Avon, certain size it does not mean the Diameter and width are going to be the same. Metzlers are a tad smaller in Dia. and taller than some other brands. Go to each tire manufacture on line and print out the tire spec charts. This is what I found for my 06 heritage, first the dunlop 150/80/1671h is 25.25 dia,6.25 width,8/32 tread. then the metzeler 150/80/16 71h is 25.45" dia, 5.85" width, 8.0mm tread depth. Now the Avon Venom AM42 150/80/16 77V is 25.20" dia,6.20" A Metzeler 150/80/16 is really a 140/80/16 in the real dia. and width compared to a stock dunlop or Avon. The Diameter makes a difference in the gearing. not to lug or to lug.
