Featureful. Reliable and extendable.
yEd has pretty much all features as Dia and a lot more! It has a bit steep learning curve and sometimes a bit strange UI, but once you learn it you can do almost any diagram in it. It can even reorganize it automatically, if it gets messy!
Simple to use and has all the options you could want. I have now adopted it for the program I have developed in Business Intelligence and Data Analytics

Draw.io is a decent alternative, but is too different. Mainly the problem is that Dia is an application program for Windows, while draw.io is a mere Web app. I know Web apps are popular these days, but they're not the same as actual applications, and personally I don't like how many companies seem to be attempting to make all programs Web apps or "online" "programs".
