If you're a student in a microarchitecture class who has to implement a core in a semester then the simplicity of RISC-V makes it a much better choice. And if you're a grad student trying to try out some idea in your thesis then you should also choose RISC-V for the same reason. If you're creating a microcontroller for a specific product then RISC-V's ability to only implement the hardware features you need is a big benefit and its compressed instructions let you save money using fewer RAM chips.
