It seems nowadays they can all reach cadences up to 240rpm from what I've managed to find... Is that in line with your own experiences?

GSC-10: Much more responsive and syncs with my Garmin much more easily. As Carleton said, the magnet will move when changing gears. Luckily, the magnet setup is pretty straight forward so it shouldn't be a crazy issue to move it around when you change gears but it is an additional thing to do. Also, given that the sensor is zip tied to your bike, it won't be too easy to move should you want to use it on multiple bikes. I would advise getting another GSC-10 if you went that direction.
Accelerometer: Only have 2 rides on it so far so YMMV. So far, I've had issues pairing the sensors with my Garmin (if anyone else has fixed the problem let me know!). I generally can't have bike computers visible on the track so it's hard to see if it's pairing properly. Also, a lot of people have these sensors on their bike at the track so I can't tell what signal I'm picking up! In other words; I need to debug. Otherwise, the setup is dead easy. Simply strap them on and you're ready to go. If you want to use them on multiple bikes swapping them is a piece of cake as well. Performance wise, while accurate, it doesn't seem as responsive as the GSC-10.
Very interested on this. What's the cadence sampling rate with the Garmin 500? Once per second? And is that the same for both GSC-10 and accelerometer?

Obviously the new generation of Garmin sensors are out there (I have a Garmin 510 with the combined GSC10 sensor but sought to separate for reasons that Carleton poined out) but I came across some issues with them from a sprinter's point of view. I can't recall specifics but I do know they got crossed off the list of options. I ended up with a set of Sigma sensors and they have not been a problem at all and were only about $AU15 (+shipping) for each sensor as they were on special at the time.
So the Sigma sensors that you have are both magnet-based with fork-mounted speed meter and chain stays-mounted cadence meter? How quick is the sampling rate? Although if it is good for you as a sprinter it should be good for me too
