I like my Sram X9 stages because it takes about 30 seconds to switch it between bikes and recalibrate.For every person I know with a good Stages experience, there seems to be one with a bad experience - I quite like the Powertap stuff as I have had good experiences with my 2x road hubs. The new pedals are interesting even if it means messing around with different cleats.
I suppose a hub based system would be just as easy but are heavier. The stages is also good because it works on my direct drive trainer and also measures cadence.
