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.

Waynefia,
Thanks. that's a good explanation/example.
At this point, and with my budget, the HK works so well I'll be keeping it. It also has the the record clamp/weight that helps dampen the whole thing and flatten some mildly warped records.
When I replace the noisy RCA cables, does anyone have a ballpark price that I should be looking for?

Thanks again for all the responses.
Both! I have a Harmon Kardon T55C with a Grado MC+ mono cartridge and a mint (except a few scratches on the dust cover) Dual 721 for regular playback. The best tables I've owned and I've had new tables as well. But if I had to pick the Dual 721
Tough call
I've owned both, the T-60 is better, sounds very much like a Linn Basik. Put a Nagoka MP-150 on it and you got 90% of what you can get at 10% of the cost.
Cheapest table I've heard that IMO worth buying over a T-60 is 2K Pro-ject Perspective with their killer 9cc tonearm.
