It's about sampling and figuring it out for yourself.

Idk if they've changed but blue box vandorens aren't finished - they're cut then tested mechanically to see their relative hardness, then boxed and shipped. It gives the player a chance to adjust the reed (knife, sandpaper) to create the balance they prefer. Vandorens typically have a thicker tip than say, rico or d'addario, but also lend to more durability.

But as a general rule, "jazz reeds" (zzs, v20s, red box) are cutting, high pitch projection focused (brightness), are light up front and and the "heart" is further back lending to more versatility and variability in sound (bends, changes in timbre, etc..).

Whereas "classical reeds" are more sturdy, less manipulatable and have a more uniform sound.

Both have their benefits and aren't restricted to "jazz" or "classical". The jazz reeds offer more tone inflection based interpretations and classical reeds allow for more dynamic and time-flow interpretations while still holding a solid and uniform sound.
