IMO the best one is the XZ+ (the one I have) because I am not a fan of the sunroof and I have had automatic headlights and rain sensing wipers in my Brezza, both I can leave without. The base version doesn't have the infotainment screen and the side view mirror adjustment.

@Vaebhav Bhatter sure. I will try and answer all your questions. Ownership experience: I am happy with my Nexon EV. I am getting 170km range which is ok for me in the city. The drive is a joy with the acceleration and one pedal driving. There is no noise in the cabin. I did not have to pay for the first service. On the negative side, the app does not work mostly (I do not use it anymore). My charger became faulty all of a sudden but it was replaced under warranty. The entertainment screen is a bit laggy. The Distance to Empty (DTE) reading, which is the range remaining is rubbish, I go by the % of charge remaining. So that's not a big issue. I don't know what update was done on the car. I am not even sure if anything at all was done. I saw a difference though, the regen was softer. Range did not really change in city driving. I am yet to take a long highway drive. I went to Pune from Mumbai earlier. I could complete 139km with 21% remaining. This was with 4 people and AC totally turned off. I got fed-up of BS in those groups and quit. It is mostly noise. One starts something and rest join the chorus. Of course Tata dealership is kind of clueless but I have received good after sales service. Although I am relentlessly pushing Tata Motors EV on twitter and sometimes in less than polite language, I am happy with my decision. I am available here and on twitter. Do reach out if you have any specific questions. I will be glad to answer all of them. :-)
