Explanations of why make learning much easier and more complete than just knowing "Sean Lavery prefers them."

With the very loose motor restrictions now, hunting for the most power out of motors is less important than it used to be (plus the old FP beat the 550s in that regard, anyway). So even though the 550s have more total power than the 9015s, we opt for the 9015s for a few reasons.
For high torque applications, we gravitate towards the CIM family of motors. Thus the higher stall torque on the 550s over the 9015s doesn't really come into play.
We'd consider the fan cooled 500 series motors for high speed, low torque applications. However, I have yet to find an application that actually needs anywhere close to the ~19000rpm free speed of the 550. The ~16000rpm free speed of the 9015 will typically let us to get the desired speed for our application using less reduction.
Last, but certainly not least, we trust AndyMark products and customer support a lot more than we trust BaneBots products and customer support. While the 540/550 family never had the issues of the 775s or other BaneBots products, we usually try to shy away from risk that could cost us a match.
