High mass vs Low Mass Turntables - Sound difference?


As I am recently back playing with analog gear after some 15 years away, I thought I would ask the long time experts here about the two major camps of record players -- high vs low mass-loaded-type tables...

For example, an equivalently priced VPI table (say a Classic, Aries or Prime) versus a Rega RP8/10 or equivalent Funk Firm table...  the design philosophies are so different ... one built like a tank, the other like a lightweight sports car...

Just wondering if the folks here have had direct experience with such or similar tables, and what have been your experiences and sense of strengths and weaknesses of these two different types of tables.

 Are use and early 12 inch version of the WT arm and it works very very well. I think the idea being that the silicone is Rigid enough that the fine movements of the stylus are not going to knock it out of place. 
 My only beef with it is that it does not keep consistent azimuth  across the record.
