In my opinion Baga/Calangute has for the best part of a number of years been very busy, hectic, chaotic call it what you want but it all amounts to the same.
There has been an increase of 'local tourists' the last couple of years specially around the Calangute steps area but as a whole I can't say that both these areas have become more busier (whatever you want to call it) than previous years.
For example, if you visit the Baga Road/ Titos Lane area at weekends, yes it is chaotic but during the week it's nowhere near as bad. Calangute High Street is busy any given day but that's exactly what it is, a High Street. Move away from these areas to the back roads and it's as quiet as most places. As I said, this is just my opinion.
It'll be interesting to get other peoples views on this.
