Which should you pick?
Eleven v4 costs 7 credits (headline rate) and Cartesia Sonic 3.6 costs 4 credits (headline rate). One of the two does not publish what a full job costs, only a headline rate, so these two figures are not a like-for-like price comparison.
Eleven v4 holds the stronger leaderboard position (#2 in text to audio against #4 in text to audio). Those are two different leaderboards unless the category matches — Versely ranks each capability separately.
