RUBY ( 'DOC ) IS THE BEST RUBY AND NO ONE CAN PROVE ME OTHERWISE
I rewatched Steven Universe because I remembered of how much I loved Garnet and the Rubies when I was a kid. Now that I watched the original, uncensored version of this show, I can properly claim that Ruby ( also known as 'Doc' ) is the best Ruby and that her title is indisputable.

PART I : A TOP GRADE RUBY
PART II : PYROKINESIS SKILLS

Did you know Rubies can generate heat and get really warm ? This can occur both on purpose and whenever they feel a strong emotion. This means Ruby will be able to keep you warm in Winter, and there is no doubt in my mind that an aroused Ruby would get really hot. With the higher-grade qualities she developed from being a Captain, Ruby will be able to regulate her body temperature despite her excitement to make sure you don't get burned, she will also engage in temperature play with you while keeping things under control.
While all Rubies can generate heat, this kind of activity requires a lot self-control, awareness and a true emotional bond at the same time, which is not achievable for most Rubies, not even Ruby ( Crystal Gem ) who too often sets things on fire by accident when feeling excited, happy or angry.
PART III : THE IDEAL RUBY

Forget pussy from a girl gem who is evil, think about dick from a gem who is able to properly identify your feelings while controlling her own.
Ruby is the most compatible Ruby for a human : she can easily find out what kinks and positions you enjoy the most, what penis shape is more adapted for the sensations you're looking for, what pace is the best for each situation, if you're truly enjoying the moment or if it hurts too much & needs to stop immediately. But the latter rarely would happen with her.
CONCLUSION

No other Ruby beats this level of compatibility, you literally would have the ideal relationship imaginable with Ruby. Also, fun fact : Ruby's actual nickname should have been 'Hearty', because her gemstone is placed on her heart and despite being a mineral, she has a big heart.
