Our thoughts:
The RD-M7005M is a solid choice if you want into the Advent MX ecosystem without stepping up to the Pro price point. You get the same strong clutch and compatibility, but with a steel cage instead of aluminum which adds a bit of weight (435g vs 358g on the Pro) but also durability against rock strikes. If you're building a capable trail bike on a budget, this derailleur punches well above its price.
