That mainly depends on the zones. KR emphasizes passenger amenities, too. So there are trains from Madgaon, making it the hub. SWR is solely focused on its HQ and freights, so Vasco is neglected.
I've been to Goa, and I think even in real life, some parts are overhyped, and some parts are not much explored. But isn't it the same for everywhere else, me myself hailing from a 'tourist city'.
