My mom. Definitely.

Bruce Lee had the fitness worked out, regardless of the arguments of how much/how little he knew - He had the physical aspect worked out to where he could have looked incredible doing ANY form. He also had the creative mind to attempt to expand his knowledge - Successful or not, I’ve seen some pretty pathetic attempts to emulate this 
I’ve also seen some really good attempts as well.. He seemed to have believed in expandng his knowledge of all things though, rather than the current trend of simply mixing and matching styles.
Well id be mad if i didnt say my teacher. Sifu Yau - Lok Yiu Lineage.
At 63 his structure and timing still make you think hes a strong guy when he aint 
Heres a pic from the late 70’s when he was in a few independent HK films -

Gary Lam / Clive potter / Sifu Bayer (sp)

Quite a broad question really. But thats my lot.

Master Samuel Kwok has by far been the most impressive wing chun practitioner that I have had the distinct pleasure of training with and crossing hands with…I, of course, still have to give Grandmaster Ip Ching the hugest amount of respect!!!
Moses
Wong Shun Leung and Philipp Bayer
another predictable thread
Lots of folks will list their sifu and/or their sigung. Plus, there are experience differences in
who really has seen what when and how.

Difficult to give an order but…
The people I study with and keep going back to must impress me!!! Trevor Jefferson, David Peterson, Lun Kai.
In only met Barry Lee and Wong Shun Leung once but they both impressed me with their skills and attitude.
Ip Chun, Ip Ching and Tsui Shong Tin have unique skills that impress me.
Duncan Leung, Robert Chu, Alan Orr, Ernie Barrios, Gary Lam Sam Kwok & Gwok Gai Jan would also be on my list.

http://www.youtube.com/user/ysiddiqui[/QUOTE]He’s Michael Louison from the WSLVT line.
Mainly from sifus: Nino Bernardo and Ng Chun Hong according to his website.
I only have first hand experience of Alan Orr and Alan Gibson teaching in a seminar setting and very much liked their teaching style.
There are some really fine clips (and DVDs) of Alan Orr sifu teaching Chu Sau Lei WCK body structure.
Similarly there are some good clips and DVDs of Alan Gibson sifu out there. I’ve got to say the WSL line of teachers are very impressive with their directness.
Best wishes,
Chee.
This is off the subject but what’s Gor Sao?
gor sau is like free application chi sau
I have seen many , trained with many , some might say a few of the big names ..
been around the globe a bit as well
to answer your question … based on ‘‘hands on’’ directly with the main individual or senior students [ which is really the true testament to a persons training methods ,how well they can pass it on to the regular guy , not just how special that one individual may or may not be ]
and as far as Im concerned there is no best … best in respect to what ? definitely not fighting none of these cats are out fighting most are to old or just not interested .
so you got some guys good at Chi sau which is 90% trickery or set up that only exist because your doing ''chi sau ‘’
some are good Technicians in the training methods of there particular system or approach ( since they set the rules and create there individual nuances of course they control there game )
some are flashy and entertaining
so the ‘‘best’’ you can hope for is to enjoy what ever ‘‘show’’ you signed up for 
I still didnt find one who do 60% of what the ancient kuit recorded. I dont find doesnt mean they dont exist.
Keep looking still.
Philipp Bayer
William Cheung, when I first met him back in 1983,84,85…simply incredible at that time. Including having the best, strongest, fasted, and most versatile kicking arsenal I have ever seen in any wing chun guy to this day - with the lone exception to that being Bruce Lee…although William’s overall wing chun arsenal left Bruce in the dust, I’m sure.
In fact, his overall knowledge and skill level of wing chun (be it TWC or Center-of-mass wing chun) was beyond anything or anyone I had ever met, touched hands with (ie.- Moy Yat, Victor Kan, Mak Po)…or seen in books, magazine articles, or videos.
I regret the fact that William has pretty much dropped COM wing chun from his program as the years went by and began only teaching that which is markedly different about Traditional Wing Chun (TWC)…different than COM (ie.- the blindside strategy and it’s corresponding footwork, central principles, etc)…
as an MMA guy at the present time - which I prefer to understand as “Multi” Martial Arts rather than “Mixed” Martial Arts - since the latter now cannotates a certain type of technique program that I prefer to go beyond - SUCH AS ADDING WING CHUN INTO THE MIX (as well as lots of catch wrestling)…
as such an MMA guy - I prefer to MIX both approaches to wing chun.
That said, the elements of TWC clearly dominate my total wing chun package.
And a very honorable mention to people like Wong Shun Leung, Gary Lam, and Duncan Leung - the training vids I have (or have seen) by these three being top shelf examples of COM wing chun.
sifu jose grados
my sifu mark hobbs for sure the best I’ve ever seen and practiced with.
A very good “practitioner”-apart from sifus and sihings
The late “Moe”- he was better than Larry and Curly

the best wing chun master i ever saw is without a doubt sifu sergio iadarola

joy chaudhuri[/QUOTE]Joy,
C’mon. Larry is definitely the top stooge. ;)
