The
ES secondaries (and
AS hot-stamps) are actually probably better for real life tournament applications, utilizing a single spot pattern across all chips. Minimizing visual variables generally works better for tourney chips, which is why many good tournament sets are either solids, contain only one spot pattern, or use minimalistic inlays or hot stamps.
Decent spot patterns and color/contrast combinations in both of those sets, with the only weak chip of the bunch being the
ES secondary T100 (despite two attempts to improve it from the original inspiration chip).
But the
ES primaries are a much better collection of individually great chip designs that still work well as a single cohesive set, plus the colored inlay is vastly superior to the grayscale image of the secondaries.
Imo, of course, ymmv.
Your turn.
