I think both options are good. Fixed distribution guarantees fair pay, but it will always be small. While the stake system pushes you to work more to get more tokens. That is why I like both of these options.
Recently, I have noticed a very popular trend, when Bounty companies do not comply with the terms of the transaction. After completing a bounty company, participants always receive a lot less reward than promised from the start. As an example, companies like ADAB, MenaPay, Dabbling and many others can be cited.
