People often say that one advantage of pedals is that they're easily swapped between bikes but users often end up buying several units for different bikes anyway. I used to swap my PT wheel between bikes (and that took just seconds) but then I ended up buying another PT.
Concerning single or dual sided. I happen to have all dual sided. But I don't think it really matters, at least for training purposes. As far as I know, all power based training plans are proportional to some sort of power test, Usually a 20-minute FTP or ramp test test. As long as the same PM are used for the test as for the training, absolute accuracy doesn't matter. You could take all the values and multiply by an arbitrary scaling factor and the training plan would work exactly the same.
What I've noticed with my dual sided meters is I have a significant difference from left to right. Typically something like 55%/45%. But it's always about the same. So, if I had a single sided PM, it wouldn't matter for training purposes.
That's cuz training is one of the least demanding uses for power data.
Now, if you're going to use your PM data or FTP value in pissing contests with other people, then I guess absolute accuracy matters. Or perhaps play around with data to estimate things like rolling resistance or aero drag, accuracy matters. And of course it matters if your competing on something like Zwift.
You can estimate rolling resistance and aero drag without a power meter, but it's kind of a pain. It works, but it takes a lot longer than with an accurate power meter. As for Zwift, sometimes an inaccurate power meter, if it's biased high, is an advantage. (And on Zwift, my weight hasn't changed at all this year. Yeah, right.)
