Specific to the funding model, we both do a kind of profit-share, with the main difference being that Earnest's repayment will usually happen earlier (assuming the business is successful) but is capped, Tinyseed payments would be smaller in the earlier years and keep growing over time perpetually. Neither one is "better" and I probably wouldn't advise founders to choose between an offer from both on the basis of just the funding model. If you're successful with either model you definitely won't be upset about the details of which model you went with.
