Considering Revising My Tonearms. Input On This Option Considered

A couple of days ago I let my recently acquired Triplanar VII U2 go. I have been thinking about my current collection of analog bits and pieces and have been trying to decide on how I want to move forward. First table is a SOTA Cosmos Eclipse with a SME V of unknown age on it. The second table is a Scheu Audio Das Laufwerk No2 on it with a Schroder CB-1L arm. There is a provision for a second arm and I do have a Dynavector DV505 I will put back in place. The removable headshell lets me play with cartridges a bit, and I find that a desirable option. 

I would tend to think the SOTA is the superior table, but so far the differences between it and the Scheu are minimal. The question I have been considering "Is this related to the SME V?" What will it take to improve upon it, and are the differences significant? 

I guess the final question is does it make sense to liquidate most items and pare this down to one turntable? At what level is there meaningful improvements over the SOTA? If so, is the Schroder competent enough to be carried over. 

If I did replace the SME V on the SOTA, I do have a line on a Graham Phantom II that is an option. The layout of the SOTA armboard limits things to a 10 inch arm or shorter, and weighing less than 2.2 pounds. 

Cartridges I have available are an Ortofon Verismo, Transfiguration Audio Proteus, Ortofon MC2000, Kiseki Blackheart (1st generation), and Audio Tekne MC-6310. If I pared things down to one table it might limit me on what cartridges can be used. 

Thoughts and considerations are welcome. Right now the thought is do I obtain the Graham and put it on the SOTA or do I revamp the whole set up?
