Hello! i help organize and run several events here in Arizona and attend many more. In my opinion this is a loaded question and the best answer I can think of is that it depends in where you live and the agenda of the event. Here in Arizona there are a quite a few right at the end of summer and many more travel from out of town to the events and more as the weather begins to cool. in general you don't want to compete with other events relating to technology even if they seem to be "non-compete" because you force your potential audience to decide which can reduce your attendance..and you will also lose the opportunity of having that other host attend your event. I hope this helps a bit. Please submit more questions :)
