Cheap vs premium drone components what’s actually worth it?

I’m building a drone for my college project and I’m confused about components.

Is it actually worth spending more on premium parts (motors, ESCs, flight controller), or are budget components good enough for a stable build?

I’ve read that a good FC + ESC stack helps avoid issues, but not sure where to invest and where to save.

Also, where do you guys usually buy reliable drone parts in India?

Would appreciate any suggestions on: What parts are worth spending on?

What can be budget-friendly?
