Depends on your market. If you want a high end server/workstation class processor then openPOWER absolutely has an advantage because they have a shipping product that is (somewhat) competitive in that arena and despite the risc-v promises the products look like early 2010 era arm server machines. OpenPOWER have 30+ years of instruction set and architectural tuning to fall back on, and that is nothing to sneeze at if you actually want good vector perf, a stable toolchain, or a roadmap that doesn't depend on VC's staying in the game.

On the other hand if you looking for a small embedded one off solution then sure, risc-v. But unless your already sold on risc-v, there are a lot of other competitors in that space which have such a huge breadth of product offerings that it might be hard to justify a risc-v solution solely based on the processor architecture.
