Try to avoid Realme 9 Pro Plus and One Plus Nord CE 2 5G if you are buying from 5G perspective. Realme 9 Pro Plus has only 5 5G bands(confirmed from Oppo Noida factory, don't go on Flipkart and Realme website), but camera is best in this price range. But I still feel it over priced by huge margin. One Plus Nord CE 2 5G is lacking band 28 for 5G which is going to be important 5G band in India. From 4G+ perspective you can buy both the devices. But should have been cheaper by 3000 and 2000 atleast. Oppo Reno 6/7 5G supports most of the 5G bands and CA is better on those devices.
