I grew Celebrity for the first time a few years ago, because a friend said how much he liked it (it seems to be a variety commonly sold in the greenhouses locally); for whatever reason, most of the tomatoes fell off the vine before they came close to ripening, something I've never had happen with any of my tomatoes.
I did grow Carnival in the past and loved it though -- as I recall, it's pretty closely related to Celebrity. Unfortunately, I don't believe that it's available any longer (or, if it is and someone knows of a source, I'd love to be able to get it again). It wasn't just good tasting, and a nice slicing size (not humongous, but pretty large and a very nice shape), it was really pretty, with sort of a "sparkly" look to the skin.
