I'll second that opinion.  I don't use any of these myself, but I work with
someone who converts my designs to Eagle.  That program makes THE most
illegible schematics I've ever seen, and zooming in and out is a real pain.
Plus, it is a bit glitchy, as you will think you've made a connection, but
it might not (for whatever reason) actually connect the trace on the PCB.  I
wonder how many layout errors on Eagle are user errors, and how many are
Eagle glitches?
