It is a decent offering. You can also check out
Poco M4 Pro (AMOLED) and save ₹3k if you don't need the 108MP camera. Almost similar specs.
I think the launch price is including card discounts.
realme 9 Pro is great.
You can also get
realme 9 Pro SE at same price if you have SBI Card.
Yes, realme UI is great compared to MIUI. Also, 9 Series comes with Android 12 out of the box. Meanwhile, MIUI is full of bugs.
