Functional asymmetry is a reality for the vast majority. I know the "you only need it to be consistent, not accurate" argument. I used a stages demo arm for several weeks, comparing it to several powertap wheels that were within spec and checked accurate with static torque tests. For me, the stages was 5% off -- the +/- 2% plus my left dominant leg. Sure, it was consistent, but looking a kjoules to help monitor calories -- which is one of the main things for most amateurs who are only training 12 or fewer hours a week -- was pointless. The Normalized Power numbers were also wonky, and Stages take on that is that they don't see NP as a valid metric (even though NP numbers for all of the other major players' gadgets will line up within a few watts of each other).
I'm not bashing on Stages -- I've seen similar wonky-business with ride files from guys using left-only garmin vectors. imho, single-sided devices are gateway devices, and once the user starts to pick apart the numbers to get beyond the basics (and if you just want the basics, the Stravanator will do as well as a single-sided PM), the more they start to look at two-sided devices or a PT wheelset.
If you have a discount card, get the two-sided pioneer. It will do its job and you won't end up second-guessing the data at some point.
