Tenor OTL vs Hybrid

I believe there will be plenty of room for both. I own the OTL's and will get a chance to hear the Hybrids in the next week. Until I hear them in my room I won't believe one amp is superior in everyway to the other. Also, when people do the comparison, how old are the tubes in the OTL's? I'm working on my second set of tubes in a year(they run 8 to 12 hrs a day). Because I use the amps in my
business the Hybrids might make more sense. That being said, everyone who has heard the Tenor OTL's in my system has loved them. Lets get some feedback from both sides.
