which is best IDE for STM32.

[AR.7]

I am using only I2c ,USB and I2s in the STM32 MCU. May I know, Is there any other IDE that is better to replace STM32cubeIDE or it is the better choice.

It's a matter of opinion. There is no "best" IDE. STM32CubeIDE is a fine choice.

It's usually the one your Boss or Customer tells you to use, or is willing to pay for.

They're all relatively serviceable, what you like is a personal choice, but learn to be adaptive and tolerant of external drivers/reality

I agree @TDK​ comment. As addon depends:

+ How many $$$ you're ready to pay for. STM32CubeIDE is free of charge ....

+ What is your favorite OS. STM32CubeIDE supports Windows, Linux & MacOS ...

+ Target devices you're looking at. STM32CubeIDE is ST made so most up to date ...
