I was in Koh Samui about this time two years ago, here was my take on it, I was there with my ex-GF (big mistake), so I wasn't doing any gaming, but I did see a lot of hot women there. Most of the Thai chicks seemed to be p4p, there were a lot of hot Aussie chicks, with a sprinkling of Israelis, Scandis, and western Europeans. There were some very hot Russian chicks, but they all seemed to be with boyfriends, a few of which were monstrous guys who looked like they could have been mafia.
So I did see a lot of hotties, but that said it was pretty sausagey over all, a lot of dudes in most venues, and like PartyTime said there were a shit ton of tall, buff, handsome Aussie guys running around 24/7 in tank tops. I have heard that Samui as well as Phuket draws a lot of Aussie body builder types, which seemed to be the case. I can't speak to whether these guys have game, but when you're in a venue full of tall, buff, handsome dudes, it always makes the game a bit tougher.
Koh Phangan was different than Samui, but similar in some ways. Here is my take on it, the entire party scene is located in Haad Rin. Haad Rin is an absolutely ugly dump, with a crappy, trashed beach, but there are a lot of hot girls who go there to party (esp. for FMP). In Haad Rin the hottest girls are by far the Swedes and the Israelis, but there are also tons of Aussies (all of Thailand is invaded by them), some okay Brits, and a mix of everything else. While there are a bunch of Israeli girls and they are hot, they seemed to roll in big groups, and are really social circle oriented, and can be somewhat closed off to outsiders, although they may open up if you are Jewish or can pass for being Jewish.
Koh Phangan like Samui is also a bit of a sausage fest, I was there for the FMP and I would say it was especially bad then, some where in the range of 2 guys for every girl. To get laid on Haad Rin, a guy needs some combination of really good looks and very "outgoing extroverted party game", with possibly a high volume of approaches. Ofcourse you may do fine just based off solid game alone, or get lucky and spit at the right girl who likes your style and is DTF.
Personally, I am more of a "low-key chiller type" so I didn't really like the Haad Rin scene although I probably would have had I bedded a hot Swedish girl. If you want to chill at a nice beach (you are in Thailand, why wouldn't you), then Haad Rin is NOT the spot. I highly recommend staying a day or two at Haad Yao, or at least catching a taxi and spending the day there. Haad Yao is a very long stretch of beautiful clean beach, with palm trees, clear blue water and a reef full of fish to swim to easily maybe a couple hundred feet from shore. Haad Yao is not a big party spot, there are a couple bars where people hang out at night time, but not especially great for gaming or SNL, but it is possible. Your best bet may be to try to holler at women at your hotel or run day game at the beach. Also in Haad Yao like Haad Rin there are spots where you can buy magic mushroom shakes if that interests you, although I never did.
Finally, I didn't make it to Koh Tao, but I regret not going, my plans changed, my GF at the time came out to spend her college winter break with me, and so I went back to Samui to meet her there and ended up spending more time than planned on Samui and Phangan. From the sounds of it, Koh Tao is the most beautiful, pristine, and chilled out of the islands, although it doesn't have as many girls and as much nightlife as the other islands. That said, everyone who goes there is still on vacation, so I'm sure the local bars fill up at night time, and since it isn't as much of a party spot, it will probably be less of a sausage fest, with less competition, and therefore may be easier to open, game, and bed women there.
