This site has been a useful tool for me to meet people I wouldn't normally run into. I've gone on about 5 or 6 dates with people from match and they all looked exactly as they posted. They were also genuine in that they're personalities were pretty much as they were described. I never really ended up clicking with any of them, but that's not any different than regular dating. Sometimes it works, sometimes it doesn't.
I'm not sure what people are talking about with "fake winks" or scam artists. It might just be that they have low self esteem and dismiss a wake as being real. I can personally say I've never seen a fake profile on match, and quite frankly they have such a huge number of subscribers that it would be a waste of their time and money to do so. Most of the people that complain about this site would complain about any dating site. Put another way, if you aren't someone people would like to date going on a dating website won't change that.
Match is great for searching for what you really want and being able to preview a person before you make any contact. I also tried eharmony and I didn't really like that site. They would match me with a few people that I really had no interest in. That is where I think match has an advantage in that it allows the user to customize the site to the way they want it to be.
