I'm in favor of total dive time rather than number of dives. That would even it out for rec divers and tec divers, both OC and rebreather. If you also had the number of dives, that would put it into perspective.
I'm a rec diver and have been logging my dives since 1997. I have just over 1820 dives and just over 1793 hours, 59 minutes/dive
There is a value to the gear up and down process, dive planning, site variety etc that total time does not reflect. A 3 hour CCR dive is all good, 3 dives of an hour each on CCR there is potential for more experience gained in the whole process.
Both quantity and total time help paint the whole picture, along with variety of conditions etc
