IMHO alphabetical is much better if you already know what you want to do. I want to do Noise Reduction, I open the Effects menu and click on Noise Reduction, which I can find very quickly because it's alphabetical and I know the name. If it were sorted by category then I would have to know beforehand not just the name of the effect but also the category it's in, and from experience with other programs it can be pretty arbitrary/subjective/confusing to have to remember the plugin -> category mapping for every plugin I ever use. Otherwise I have to parse a bunch of categories and think "hmm, I wonder if they would put Noise Reduction in here..". Either way it's slower and more of a hassle.
