Why We Do Not Rank the Brands
Because a ranking would imply differences our own checks do not find. Where the underlying game is the same engine, the odds and lane tables are identical, and the only genuine variable is which operator holds your money — which is a question about that operator rather than about the branding on the icon.
A ranking would also be stale within a year. Names rotate for the reasons above, so a page listing today's versions would spend most of its life describing products that no longer exist under names that no longer resolve.
The Practical Version
Open the lane table, look for the studio name, check where the deposit goes, and treat the brand as a label rather than as information. Two minutes of that beats any amount of reading about which version is best.
How the underlying round works, whatever the logo says, is on the round explainer, and the full guide list is on the home page.
