Yes, one of the toughest things to do would be to rate the Windies quicks in order.
In my time I've seen:
Wesley Hall - classic quick bowler
Charlie Griffith - possibly the quickest of them all, but a very dubious action
Garry Sobers - could bowl very quick when he wanted to
Andy Roberts - possibly the doyen of Windies quicks
Michael Holding - whispering death, such a beautiful smooth action.
Colin Croft - brutal speed delivered from wide of the crease
Joel Garner - good pace and could get the ball under the chin from a good length due to his height
Malcolm Marshall - swung the ball both ways at tremendous speed
Curtley Ambrose - sensational bowler, could do it all
Courtney Walsh - not express pace but a wonderful bowler
Apologies to other quicks who don't readily spring to mind.
Patrick Patterson, when he was on song, apparently very nasty to face.
God, looking at that list of names, there's simply nothing that good in terms of sheer numbers from any nation.
