Hi there!
What are the best IMU and barometer online?
For best I mean the most precise, "battery-friendly", and obviously as cheap as possible - even if I have quite a bit of budget.
I ask here because I can find the specs online but others' experiences is better!
Thank you
All of your "BESTS" are mutually exclusive. Please be a little more free with your actual requirements.

I'd like to know others' experiences to understand what IMU and BARO buy.
Precision is the main aspect to consider obviously.
I need them to vertically land a rocket from 10km of altitude in a precise target.
Fascinating!
Can you take a moment to describe the rocket flight control system, and its capabilities in terms of precision?
How will the IMU fit in?

One of my customers has an oxygen supply system for light aircraft. Their engineer tells me their barometer can detect a 15 ft change in altitude. I do not know what the part number is as they keep all their component stock in-house. That is probably the best you will be able to find and will require you to make the interface electronics.

I think that I'm gonna use BMP280 and MPU6050. They are very cheap and they seem to be the best ones.

Sorry for the "little" delay for me to answer.
It's going to be soldered on a PCB designed by me into the frame of the rocket itself.
I hope it to get preeetty precise bc I want it to land vertically on a precise target (like a Falcon 9 scaled).
The Flight Computer should become able to handle TVC, fins (to control the landing) and the fuel flow into the engine chamber.
