For this exact setup it doesn't matter as the whole cable is unbalanced due
to the 3.5mm connector being unbalanced, but for the future maybe an
XLR-XLR-cable will be more useful. That is if you want to get into higher
end equipment in the future. And as you mention those cables are often
more robust. Though, is it a robust kit you need or a small and light kit
you need?

Fwiw – I have tried to extend a plug in power microphone before using a stereo
3.5mm cable and it did not work – ended up having a lot of noise and hum.
Apparently plug in power over long cable lengths is not recommended. Have not
had any issues with long XLR cables using phantom power.

I ran a long unbalanced pair of cables and got a local radio station as a
bonus. :-) I also got mains hum from my 33KV electricity pole ground which I
could measure with a meter. Part of the pickup was from the XLR shells
touching the ground.
With 3.5mm extension leads, theoretically these should be individually
screened (usually fig-8 profile).
Weight can be an issue, but if the long length is an extension lead, that's
another pair of 3.5mm connectors to come loose or crackle. The trick is to
tie an overhand knot over the junction which stops it pulling out.
I solved the interference problem by making up a
unbalanced/balanced-floating transformer box. Transformers are out of
fashion but they work.

"I�m connecting my AT822 stereo mic to my Oly LS-10 and I want to get an
extension cable so I can place the mic where I�d like and retreat to a safe
distance. The mic cable is 5 pin XLR to 3.5 stereo. Would it be better to
extend via the XLR or extend the 3.5mm stereo?"
Definitely the XLR.
"I�m thinking the XLR since it�s more robust and probably less susceptible to
cable noise. "
XLR connectors are infinitely more robust than mini phone connectors. Noise
rejection won't really figure into this, since the line is unbalanced at the
mini plug end, but the XLR is a locking connector whose pins make much better
electrical contact than the mini plug.
"Does it matter? "
The XLR connection is a much better electrical interface than any sort of phone
plug, whether mini or 1/4".
"I�m looking at Hosa cables sold by B&H. Are there any others I should be
looking at?"
I would recommend looking at any brand other than Hosa. It is cheap crap & has
failed on me on more than one occasion in professional concert applications.
Stick with Neutrik or Switchcraft connectors on Mogami, Canare, Gepco, or
Belden cable & you will have a professional quality cable.

You must have had a wiring problem. My “light system” uses cables over 100’ for
four channels of PIP mics and works perfectly.
