I don't think so, certainly not when we're talking about multiple GT victories.
Just compare Roglic to some of the Tour winners of the past 20 years with a single victory, i.e. would anyone say these guys had better careers & more prestige than Primoz Roglic? For example Wiggins, Evans, Sastre, Thomas or Pereiro. I'd take 3 Vuelta wins in this era (& all of Roglic' other victories) over 1 Tour win.
I also think in this current cycling epoch where races are televised on Eurosport & easily accessible everywhere, the Tour de France is no longer the massive crushing "behemoth" it once was. For example even Froome totally benefitted from diversifying his GT portfolio & winning the Vuelta/Giro when that was unthinkable just 15 years ago for guys who won the Tour (i.e. who viewed other GT's as crud by comparison).
So nope, perhaps the Vuelta once was the lesser GT by far, but now? And considering the competition at this level (Bernal will be there)? I think the Tour result is disappointing, but that will quickly be forgotten "if" Roglic can take Vuelta number 3 next month.
