The old article asked which promotional label was better. A useful answer depends on what the offer provides and what restrictions accompany it, rather than on the words free or credit.
Different units need explanation
A credit balance, a specified number of spins and a temporary promotion can represent different things. The stake value of a spin and the games on which it can be used are relevant. A large count without those definitions is difficult to compare with another offer.
Conditions can change the meaning
Eligibility, expiry, permitted activity and the treatment of winnings should be read together. Do not assume that an offer can be claimed unlimited times or that a promotional balance is unrestricted money. Those broad statements from the original article have been removed.
There is no universal winner
A promotion's practical meaning comes from its own conditions and the amount of activity it requires. This archive revision does not provide an active offer or a recommended operator. It also withdraws the suggestion that a bonus increases control over a random outcome or makes additional spending a sensible way to obtain a reward.
