Not a direct comparison, but I have a Tango 6 1-6x24 FFP with the MOA Milling reticle.
It is an absolutely rock-solid piece of hardware. Remarkable optical clarity at all magnification levels, excellent low light performance.
Once I set my zero on the dials, adjustments are lickety split with their markings.
I have not tried it past 300 and have complete confidence it would perform as long as the magnification is suitable for me.
Personally, I do not care for illuminated reticles because most don't get low enough where they do not affect your sight at low light. The Sig does get low enough.
Their Motach motion sensor to shut off the illuminated dial has saved me replacing my battery dozens of times.
The only complaint I would have on it is the weight.
