Following incorporation into India, Goa voted for a political party (which held power until the 1980s) which not only supported incorporation into India, but wanted Goa annexed into the Indian state of Maharashtra on the basis that Goan culture was a form of Maharashtrian culture and that the Konkani language was a Marathi dialect. This indicates that it was broadly supportive of incorporation, I'd say, even if the question of whether Goans are Maharashtrians or not remains controversial.
But on the other hand, a lot of this is due to the character of the Portuguese fascist regime. Goa is Hindu-majority, after all (and it was at this point as well), and so naturally you can expect that the Christian supremacist nature of the Portuguese regime was massively alienating to them especially. Beyond that, there was the impact of its authoritarianism on Goan politics. One major moment in the Indian nationalist movement in Goa was when, in 1946, the Indian nationalist Ram Manohar Lohia led mass protests against the Portuguese regime which ended with the protests being brutally suppressed and Lohia being imprisoned (only a few months after the end of his prison term in the British Raj, no less). This horrified many and discredited peaceful protest as a force, resulting in the formation of guerrilla groups in the 1950s - one of its leaders, Mohan Ranade, was imprisoned in Lisbon until 1972. Indian nationalism in this Goa may well evolve differently in this very different Portugal.
Yet, even a democratic Portugal may well be authoritarian and repressive in Goa. British constitutional government did not stop the British Raj from being an authoritarian state that regularly arrested political opponents and gunned down peaceful protestors, after all - the same may well be true in this Goa. There's also the question of trade links between Goa and (the rest of) India, and how that may affect its development.
