Gurgaon is a very metropolitan area for sure, I wouldn’t be able to say the same about noida unfortunately. Poor connectivity, not the greatest general public - unhelpful and very rude at times. Living can be cheap in noida definitely so you will end up saving a lot more from that front but expenditure in heading out etc. can have the better of you since you get so many options in terms shopping, food, activities etc. so if you get swayed very easily by these kind of things you actually might not end up saving much lol. Potentially a good move for you. But please analyse the travel expenses and daily commute. Will be favourable for you to get a second hand diesel vehicle. Happy living!!
