Eh, as a Delhite, I didn't like Bangalore at all
I'm not sure about Gurgaon, tbh, but Delhi has got MUCH better roads, an actual proper public transport system and people who are actually nice to you? Like, I got back from Bangalore after 20 days and booked a cab from the airport to my home and the cabbie called and said "Madam, Mai khada hun idhar, koi na, aap aram se aao" and he said it so sweetly, I almost cried
Change us hard, you'll definitely have trouble adjusting, starting out from scratch at a new place is tough
There's nothing NCR doesn't have that Bangalore does, but I guess, you might miss the weather ¯_(ツ)_/¯
