I once had the leupold gold ring. The ocular lense was tiny and the focus ring was so difficult to turn it made impossible to stay on target and focus on it. I since purchsed the Zeiss 65mm.At one point I wondered if I had made a mistake by not purchasing the 85mm until I borrowed one.Although you have a greater zoom capability with the 85mm, heatwaves and light gathering abilties become a problem. In my opinion,the reason for a greater magnification is the ability to scrutinize objects at a father range, but what's the point if the image becomes too dark to see clearly,not to mention the heatwaves which can distort images even on a mildly warm day.
I say if you cannot afford a new Zeiss or Lieca, look for a used one. Besides, their resale value are above the rest.My brother picked up a demo Leica from Cameraland a few years back for a great price.
I was fortunate enough to purchase my Zeiss when they were "only" $1500 with the eye piece. Since then they have dramatically increase in price, which I'm not sure why. I did see they have different eye pieces, but $2500? Ouch! Find a used one and you will. Never regret it
