Marantz 6150 turntable versus Dual 1218 turntable, which is best?


I have acquired a servo-controlled direct drive Marantz 6150 turntable and a Dual 1218 idler wheel drive turntable, and both have to be serviced.  I only need one of them, so I am wondering which do you think is the superior turntable?  I only want to repair the best one.

Marantz 6150 vs Dual 1218 is near-same as Mercedes S-class vs. Buick Century.

Thank you for your reply.  Why is the Marantz so superior?  I see that they tend to sell for about the same price on eBay.
