Its my fourth day today in Delhi, and would say that we find Delhi much cleaner and cheaper.
Metro is excellent, though they need to be more tourist friendly. Auto rickshaws are easily available, but you need to talk for the fares earlier itself before boarding them. They dont ply on meter. City buses also offer an easier way to travel. But you wont find the route guide or something similar which even the metro misses out. They should have a route guide with distance meter and approx time to travel especially for travellers. Mumbai has one. They even have apps for it. I’m not sure if Delhi has any such things, if yes, they need to market it properly, if not, they need to develop it and of course market it so people are aware and use them.
Overall a very good experience. Looking forward to many more visits, Inshallah.
