gOHM makes more sense, I feel that at the moment, it really needs to be simple and straightforward for cex users, to buy and hold/buy and forget, can be withdrawn to multiple chains, no dilution for cex users, cex can't take advantage of cex users that may be unaware of staking, index adjusted price etc.
Though the points for OHM makes a lot of sense too, this is a tough one, voted Wintermute but actually both might work.
