If you're working on a student or hobby project then simplifying the scoreboard or whatever OoO scheduling structure you use by having all instructions be 2 inputs and 1 output is a big help. Compared to the complexity of a modern core that's a drop in the bucket but for a single person or a few friends or grad students it can be a big deal. And by doing that project you're still learning the important things. So for someone in the position OP is in I'd certainly recommend RISC-V. Don't ask "Is RISC-V good or bad?" but rather "For what purposes is RISC-V suited?"
