I prefer vyb as it encourages not to power down. I like the idea of accumulating funds for retirement. I wished they both have liquidity pools on Beeswap. There is a wide margin between buying and selling orders on both Tribaldex and Leodex. So It prevents buying or selling vyb or pob instantly at a fair price. Hive/pob and Hive/vyb pools also would help pob/vyb price to stabilize. If someone creates the pools paying the initial fee, I suppose many people would like to invest in as a liquidity provider. (At least I would like to invest)
