First and foremost, I believe that its the artist not the art that makes the fight. Having said that, though, I'd like to comment a little bit about the styles...
First off, 'Kung Fu' addresses a bajillion different styles which are very diverse. To make blanket statements about Kung Fu is rather illogical because of that. But to be honest, I don't know much about most of these. There is one division of Kung Fu that I am relatively knowledged in, however, and that is San Shou.
San Shou is essentially Muay Thai without elbows and with throws/takedowns. However, there are several counterparts to San Shou. There is military San Shou, which encompasses basic standup (elbows included) as well as ground fighting. That is a form of kung fu, which would probably defeat Muay Thai in most instances, simply because it would be a standup/clinch/ground fighter vs a standup/clinch fighter. One would be versed in all ranges of combat, and the other would be versed in only two. Another variant is civilian self defense San Shou. I...can't say I know what that is, but it sounds like it would be similar to the militarized version, but perhaps slightly watered down. And finally, there is sport San Shou (this is the variant, which doesn't allow elbows).
An interesting fact is that San Shou has participated in quite a few style vs style competitions and has been relatively successful. In fact, San Shou had been pitted against Muay Thai several times and yielded good results. Now, yes, some fights were held in China. But, actually, some were held in Thailand. And surprisingly, with Thai judges, a San Shou fighter pulled out a decision victory.
regardless, I just wanted to point out that San Shou which has/can easily hold its own against Muay Thai is a form of Kung Fu. But, of course -- as stated at the beggining of this post -- what really matters is the individual.
