Interesting. I knew for many products there is actually only one or a small number of manufacturers and everyone else just puts their label on it. I would not have thought, though, that Sylvania and Westinghouse were rebadging the same bulbs as EcoSmart and Definity! (Actually, I've never even heard of Definity...)
I had a 25W CFL go up as they describe - lots of smoke and a bright flame-like flash. Was over so fast I was never sure if it really flamed or not. So far the LEDs have been fine... (Mine are all Phillips.)
