Multiplex multipin connectors are very popular with jet flyers who need high reliability.

Yes, they handle much higher currents than a servo is likely to drag but the best feature is they are big enough to solder & heatshrink properly without too much trouble. Six pins, you may need three plug/socket pairs.
Remember that, for example, if you are connecting four servos you only need six pins, positive, negative & the four signal wires.
I'm an electrician who works on industrial machinery. Amphenol brand connections are very popular & rugged, lots of pin configs available, may be a bit heavy. This is their standard product line, they have higher mil-spec connectors available:
