Not decided between these 2 powermeters. Have searched high and low but not managed to find any real world weights.

Has anyone weighed these in any format? I would appreciate some info.

Quarq is likely a more refined design, but Rotor offers 2-sided power. For that reason I'd go with the Rotor.

A lot of times I feel like there's asymmetries in my pedal stroke and I'd like to be able to get feedback on that. It isn't that 50-50 is the perfect balance but I'd like to be able to see if symmetry changes.
