Dual 721 - Harman Kardon T-60 - which TT to keep?

I have a Dual 721 which needs a little work – noisy RCA cable that has some hum and cutout on the left channel, and an ugly dust cover.
I also have a Harman Kardon T-60 in quite nice shape (but cracked dust cover).
I'm leaning toward keeping the HK, repairing the Dual's problems and selling it.
Before doing so, I want to know if I am missing something. Is one of these TTs markedly better than the other in some way?
The Dual is direct drive and some reviewers have raved about how very quiet it is. The HK is belt drive and reviews keep describing it as "the poor man's Linn Sondek".
I would love to hear your opinions.
Thanks in advance.
