Spent the last three months bouncing between Evolution, Pragmatic Live, and a couple of the smaller live dealer studios across a handful of operators. Documented every session, rated each on stream quality, table selection, dealer rotation, side-bet UI, and chat moderation.
Short version: Evolution is still the benchmark on production value and table variety. Pragmatic Live has closed the gap dramatically on stream quality and is now the better mobile experience by a clear margin. The smaller studios (Ezugi, Vivo, OnAir) are fine for filler but the dealer pool is thinner and you'll see the same faces at every table.
Detailed notes below. Long version in spoiler if you want the table-by-table breakdown. The line is the line.
