Scooter, unipivot arms are not good. Too many degrees of freedom. The VPI bearing in particular is not very durable. You here stories here of people having to change the needle. VPI now has a gymballed arm which looks very nice but I doubt that is the arm on these tables. Go to Lyra's web site and look at their recommendations. Only arms with "rigid bearings" need apply. 
I would go with the Prime besides being a gorgeous table it is a current version and the 10 inch 3D arm is very easy to set up and maintain, with that said the peripheral ring and clamp should be part of your equation with either of the 3D/unipivot arms for best results. I have never had an issue with Lyra carts on any of my VPI unipivots. Enjoy the music
I had a VPI Prime and could not stand the unipivot arm.  Every time I wanted to play a record, I had to constantly fiddle with the arm. The problem was it was always tilting to one side or the other no matter how many times I adjusted it.  I had the same problem wit the VPI Scout, but to a much less degree. I now own a Technics SL1200G and bye bye problems. 
@stereo5 , was it you that didn't like it or your wife and if it was you why did you buy a Prime after owning a Scout, they have a unipivot arm also right. The OPs question was either or or so I thought. Just sayin.
