Power meter recommendations

I had a PT. I currently own a Quarq and Vectors. I also have a computrainer.

Like you, I would not buy a PT because it's a PITA to swap around wheels from race, trainer, road training. If you don't need to swap around it is a good, cost effective solution

Based on the L/R measurements of the Vector a single side solution like Stages or Vector S would not work for me. So I think you are prudent

I have heard nothing but good things about P2Max. For the price, I would probably buy one. One criticism of the P2M is the inability to change slope if it isn't measuring properly. Probably not a problem many people will have

What I like most about the Quarq is the openness of the platform. Ability to do diagnostics, adjust slope if required.....it's hard to describe, but it's not as "black box" as other power meters. Their customer support is incredible. They do cart wheels to make their customers happy. But PT and P2M are also known to be very good. Downside of Quarq is they are expensive.

Vectors have been great in terms of accuracy, but I am always skeptical of Garmin quality. Time will tell. I do love the ability to swap them to different length crank arms. In terms of swapping, I can swap cranks as fast as pedals. I am excited about some of the metrics that seem to be coming from true L/R power meters

If budget is an issue, I would go P2M.
If budget is not an issue, quality of the data and the PM is the main criteria, I would go Quarq.
Time will tell if Vector is of high quality, but so far so good, although all indoor training. They seem very accurate.

Crank based requires a little thought planning if you plan to swap from bike to bike
Pedal based eliminates this but you are limited to the type of pedal.

I rode the Quarq, Vectors and Computrainer within 2 watts of each other.

For price range I could not be happier with my P2M. Just got one when they had Black Friday sales. Customer service has been great. I am biased as I have not used any others. Quarq was my second choice.

I bought the P2M S Type a few months back as well and love it. I didn't want to break the bank and this was a great option. I have a Cervelo P5 and it fit right on my Roto crank so easy to install and use.
