Going by Season 1, so that all of the swordsmen who have appeared by now can be counted (ie you can count Oberyn, from Season 4, but also Ned Stark, despite the latter having died in Season 1)
Also Jaime is to be counted before he lost his sword-hand. 
Poll will be up soon.
Poll Question:
Who was the best swordsman in Game of Thrones?
Poll Options:
1) Lord Ned Stark
2) Jaime Lannister (the Kingslayer)
3) The Hound (Sandor Glegane)
4) The Mountain (Gregor Glegane)
5) Ser Barristan Selmy (Commander of King Robert Baratheon's King's Guard)
6) Jon Snow (Know-nothing
)
7) Prince Oberyn Martell
8) Lady Brienne of Tarth
9) Stannis Baratheon (The True King)
10) Other/The poll is dark and full of terrors
*
Some of those saw no combat in the show (most notably Ser Barristan, but he was said to be still a great swordsman), while others fought only briefly (Ned Stark, against Jaime, before one of Jaime's thugs speared him on the knee..). Oberyn was pretty cool, and since i liked his character overall i am voting for him
Khal Drogo, btw, isn't there cause he is not a swordsman, and i don't like him anyway
