My only experience with Citrix is their GoToMeeting app/service. It's probably the most aggravating meeting software I've ever used. From almost everyone else's comments here, GoToMeeting seems to be their best piece of software.
GoToMeeting is just as bad under LogMeIn as it was under Citrix. It’s barely changed in years so I assume no resources are being invested and they’re just milking the revenue until it eventually dies.
Edit: formerly? LogMeIn owns it now: https://en.wikipedia.org/wiki/GoToMeeting
