My biggest gripe with laptops within this range is that they have terrible combination of hardware here in the models available for sale in India. There are less powerful GPUs paired with much capable CPUs or vice versa, 16gigs ram is not dual channeled, or if you find a laptop that has these balanced then it most likely has garbage thermals or terrible battery life or 60hz screen.
You will still be able to find a good laptop in this range at a good price but it will have hardware of previous generation.
Msi usually offers very good specs on their laptops for a cheap price, however they have very low number of service centers in India. I have a msi gf65 10sdr from 2020, it had very good specs for the price when I bought it, but after buying I realised it had very poor thermals.
Lenovo IdeaPad gaming is overall a very good laptop but has poor battery life
Acer nitro is good, but has heating issues and their 16gb ram variants come with single channeled memory.
Lenovo legion and Asus Rog are simply incredible, but I doubt if you will be able to find them with 144hz screens around 70k
