Garmin Vector vs power2max

[Gaber]

Hello guys. I own garmin vector pedals and read a lot about their inconsistency in power readings. I recently switched bikes so I swaped also vectors - tightened them with a torque wrench. But I feel, that they are reading little lower now. Im thinking about selling them and buying power2max powermeter. I want a consistent and reliable powermeter. Should I keep them, or sell them? What are your experiences with Garmin or power2max?
Many thanks

What means have you used to establish they are not reading correctly, or that a variation does actually exist?
