Horribe AMT lag in an awsome car

I did a test ride as I am planning to but mini SUV Automatic diesel creta brezza or Nexon. I took test drive af all. Nexon is amazing in built and the dashboard is beautiful. Nexon engine is powerful, features like hill assist and the driving modes like eco city and sport mode are amazing. But most importantly I am not buying the AMT lag is very very pathetic, I fail to understand why this bad AMT gear box is used to spoil the driving, the car actually dies for couple of seconds when there is auto gear change going on, there is lag of 2 seconds which is horrible. Best car but horrible AMT I am not going to buy, going for brezza now.
