They gilde better than the space shuttle and that got deadsticked every time it got flown (well, almost every time).
The aerodynamic properties make both high speeds possible while retaining maneuverability at low speeds tend to lend themselves well to decent (for a jet) glide performance. What they trade off is stability.
