I'd stick with what you have or upgrade to another SRM.
Data sample rate on the Garmin is much lower than the SRM BTW.
What is the rate on Garmin? Can you elaborate on your recommendation about staying with SRM or upgrading?

Battery: SRM requires soldering in a new battery every 3-400hours, with the Quarq, you unscrew a cap and pop a new battery in, 10 second job.
Waking crank up: My SRM requires spinning the cranks forward to wake them up, with the Quarq, I can spin them backwards and they wake right up. It seems pretty minor but it is so much easier to zero the Quarq at the start of the ride than my SRM.
Zeroing while riding: My Garmin 800 autozeros with my SRM, it's always dead on and means you really don't have to zero them after you start riding. The Quarq requires backpedaling 4-5 times to zero while riding.
If I were to purchase another powermeter, it would most likely be a Quarq.
Hmm, which one do you have? I have an old wired one with PCV, and I can wake it up by spinning backwards. Yeah one of the things I don't like about SRM you either have to send it in, or solder new battery in. Which is what I done last time, but battery capacity is lower (not to mention my soldering skillz are lacking lol).
