If you wanna know what markers are best then look toward who wins things, at least this gives some flavour of performance.
Pros do use markers that they are sponsored with but not many pros would use a marker that predestines them to lose...well one team did but hey, that's another story and my lips are sealed.
And so, the best markers (empirically at least) are, in no particular order:-
Egos, Angels and DM's and then my memory starts to slip a little but that's because I am biased ..... allegedly ........ the truth of the matter is, I wasn't but I am now
