Consider for a moment that Supreme Clientele came out in the year 2000 breh. That's an example of an album that was monumental & influential that "real" on any hip-hop fan for that matter would consider classic material. There is an objective consensus that goes along with classics imo. You can't just throw Tetsuo & Youth in there, especially when it's probably at best Lupe's 3rd best album. Furthermore, it's way too early to crown To Pimp a Butterfly in this fashion also.
Go ahead and appreciate the music that you love though breh. I don't take issue with that, but the "Real" hip-hop fan shyt is often a cop out for panned & obscure material.
