My impression is that Eta is a better choice, if only because it is compatible with a wider variety of Haskell libraries.
Eta is a better choice, if you care about Haskell compatibility in the strictest sense. Frege doesn't really pursue this, but the flip side is that it optimizes for working as smoothly as possible with the JVM ecosystem.
And as a sibling comment mentions, the announcement does clearly state that a rather extensive rewrite was done, including switching to a new architecture, with likely performance improvements coming from that - it's nowhere close to a pure Java vs. Clojure comparison.
