S vs SEI
Sonic (prev. Fantom) and Sei scored on the same 25 variables, ranked against the same 251 tokens, with every gap between them shown.
Scoring pass 18 Sept 2026. Market snapshot 7 Oct 2026.
What separates them
S scores 115 of 250 and ranks 84th of 251. SEI scores 100 and ranks 144th. S leads by 15 points, which is a real gap, though small enough that one variable moving would close much of it. S takes 15 of the 25 variables, SEI takes 3, and 7 are level.
One variable separates them by 3 points or more. S is clear on Buyback and Burn (4 against 1).
Both score 3 or below on Supply Inflation, Vesting Schedule, Institutional Adoption. A weakness both sides share is not a reason to prefer either. It is a reason to check whether the category itself carries the problem.
SEI still has 32.7% of its eventual supply to enter circulation against 0% for S. On the same market capitalisation, a buyer of SEI is taking the 1.49x dilution path and a buyer of S the 1x one.
SEI is valued at $457.3M against $154.2M for S, a 3.0x difference. The smaller of the two scores higher on fundamentals, which is the disagreement worth understanding before either position is taken.
All 25 variables, head to head
Both tokens were scored by the same framework in the same pass, so the numbers are directly comparable. What a comparison adds over two separate pages is the gap: a 6 against a 6 is a non-event, a 9 against a 3 is the reason to hold one and not the other.
