This applys to both platforms.
The BLOCK3 is coming with a HMD smething that does not exist on your existing fleet of 117 thunders
Also this is your first aesa radar
And the block 3 starts arriving next year its in final testing
LCAmark1a is same and will not start arriving until late 2022 or early 2023
You are right regarding HMU. But you are wrong when it comes to platform. Combat aircrafts arent worth it until they are flying and serving.
Tejas has long way to go to prove its battle ready. An american engine or an israeli radar doesnt mean its combat ready until it is trained and participates in real missions, which tejas has yet to see hence this platform is not mature enough compared to jf17.
You can brag about the dates and years for tejas but unless it sees some real action..it is a lemon.
Even the rafales you get will not be ready for combat until indian pilots can actually train them in action.
Training takes time which you are not taking into consideration.
The time and dates you are giving are not real time expectation and only good for nationalism and fanboy culture.
There is a difference in real world and bollywood.
