The honest comparison

Günther vs Quartile

Hourly autopilot, with the pricing behind a curtain.

Quartile is genuinely fast (hourly bid updates via Amazon Marketing Stream) and genuinely opaque: no public pricing at all, and the automation executes without an approval step. Their AI chat answers data questions; it doesn’t propose or perform actions. If you want speed with a steering wheel, that’s the difference.

A pricing page would be nice
