I, for one, am not fond of fixed release schedules. It's something that Canonical brought to the linux ecosystem and some projects (KDE, Gnome) adopted to appease the darling child. Other distros followed suit, but chose cycles that weren't 6 months so they would appear to be independent. Would personally prefer a regression towards 'release early, release often' instead of release cycles.
Of course, this is mostly opinion and I don't have any real objective evidence to say that release cycles are bad.
