Bourdon tube style gauges are what you want for many reasons when measuring tire pressure. This article hit on most of them. One of the negatives of the bourdon tubes are that if you drop them, they can be damaged and give you offset readings.
To eliminate the issue of clogging the gauges, fill the tires with the valve tip resting down. With good "race" sealant, you can clog the gauge in a single measurement. I have not found a way to get the gunk out of the accugauge, but I also didn't spend much time trying to repair it.
The A1 and A2 reverbs weren't very good. They went to the plastic IFP in the A2 which at least alleviated the issue with ruining the IFP tube but it did not solve the issue with air getting into the system. They put the proper IFP seal in the B1 versions and I have yet to have an issue. I could kill a plastic IFP A2 reverb in 5 months time. The B1 has been going for 15-16 months at this point. I ride a lot, that is 2500-3000 off road miles.
I've never experienced issues with either remote lever. They both have been great and I trust them as much as I do my hydraulic brakes.
I also have an X-Fusion manic with a cable actuated post. I prefer the direct feel of the reverb lever. The reverb is also overall a lighter post.
You would be crazy to pay the asking price for a reverb though. The Manic is the post to get if you are spending your cash and just want to turn miles.
