The greatest and longest lasting players are good players and not showmen. Dave Gilmour has the stage presence of a tree. Eric Clapton has once been seen to actually smile onstage, but these rumours have not yet been confirmed. Great guitarists are not flashy performers. The great musicianship of the 2 persons mentioned carry them through their shows sufficiently. On the other hand, Slash and Yngwie are performers. Great players too, but they have the showmanship, ego and everything else, but people grew tired of them quickly. They are now forgotten.
In between these extreme examples, there are many other guitarists falling one way or the other.
I think it may be fairer to say that you can't get by on showmanship alone. There have always been performers who combine, in various ratios, showmanship and playing. Not all the greats are like Gilmour or Clapton and just get on with playing their axe with no concession to flash.
Jimmy Page wore flash costumes and struck poses on stage. Jimi Hendrix was an extrovert showman with loads of tricks - playing behind his head, playing with his teeth (not at the same time as playing behind his head), setting guitars on fire, humping his gear etc. We still regard these guys as great players.
