The HpH 304 CZ in the same category or "no way".
I'm new to all this.

I think the Lak 17a performs closer to the 304S especially at higher cruising speeds. I use to own a Mini Nimbus and flying with a 304CZ, the CZ was MAYBE slightly better in cruise, and definitely a little better in climb, maybe because the 304 had winglets (also the Mini was flying with a little bit higher wing loading). The LAK I now own is quite a bit better than the Mini.

Look at the sports class handicaps to get a general idea on performance differences between sailplanes.
