To the end user, it won't matter much either way, because most open source software already compiles and runs just fine on RISC-V; there are plans for projects like Chromium and Android to fully support RISC-V. RISC-V is on a trajectory to "just work". However, what does matter is that the RISC-V ISA will be cheaper and more flexible for device manufacturers to use. That's why it's superior to ARM and has already partly supplanted it for smaller chips (there are over 1 billion RISC-V chips in use already).
