As an owner of the Aries 3/10.5/Superplatter and a 19 MKIV/Sama/10/TNT 5 Bearing and Platter, I'll offer up some comments.
The Aries I came with the TNT 5 Bearing and Platter. This is different than the stock Aries 3 platter. All Acyrlic platters are more forward sounding and higher in detail than the composite platters. The composites offer up better bass response and a more organic (i.e. whole) presentation although more recessed sounding.
The new Superplatter is somewhere in between the TNT MK5 platter and the all acrylic platters. IMO it may actually be superior to the Superplatter.
The 10.5i is a definite improvement over the 10. The 10 can have the "jitters" as it settles on a record. The 10.5 tracks audibly better. The Vahalla wiring also allows more details to be transfered to the phono stage.
Although you didn't ask, I'll through in some more comments. The SDS MUST be considered, it moves the table up a solid grade offering speed stability. As far as the outer ring goes, it does benefit many of the thinner LP's but becomes a pain putting on and taking off.
Hope this helps
