Direct drive vs belt vs rim vs idler arm


Is one TT type inherently better than another? I see the rim drive VPI praised in the forum as well as the old idler arm. I've only experienced a direct drive Denon and a belt driven VPI Classic.

to me, it looks like the Fat Bob is running very slightly fast, as the line moves very slowly to the right on each revolution. When the stylus drag is applied, the line quickly moved to the left, indicating a slowing of speed, and then stayed there, indicating a constant 33.33 rpm under load. the video didnt stay on long enough to see if that changed, but to me, it reflected a design which rendered the proper speed under load. Is something wrong with that?
disclosure. I own a Transrotor Fat Bob an like it very much.
FWIW, I use a "Jeremy" bearing on my Lenco. Jeremy is in England and makes several different versions of replacement bearings for Lenco and possibly for Garrard. I have his "Superbearing" with an accessory clamp that attaches underneath the turntable chassis to keep a firm grip on the bearing housing. The whole assembly really works. Note, I have not compared the Superbearing to any other aftermarket bearing, just to the stock Lenco bearing assembly.

Manitunc, Don't sweat it.
I'm not sweating it. Just responding to a previous post that suggests the video shows the transrotor as being seriously deficient in speed regulation. I didnt get that from the video, but if others can point out how to get to that conclusion, I am all ears.
I was trying to be supportive. I think the availability of the Timeline has created a furor that is completely out of proportion to its real significance. A case of too much information.
There is a new table called the Tech Das Air Force One which is getting a bunch of buzz over on WhatsBestForum. It has a magnetically levitated platter which I think is driven by a rubber belt. Bob Graham is importing it as the NA distributor and likes it so much that he is developing a new 12" arm called the "Elite" for the table. Two samples are at CES now. It's nice to see that someone is developing new, seemingly very well engineered turntables these days which are reaching for the state of the art. The NVS is DD and this one is belt. It will be interesting to see how they compare long term to some of the classic vintage tables discussed here.
