Shockwave.Com versus other Similar?

Tweet

I have been a member of Shockwave.com for a year now and I was wondering if anyone had found similar type sites that you would consider better? I like shockwave and it has some good strategy games that I like but I see in the review sections sometimes people mention that they play at other sites that they enjoy more but they can't post what they are and I haven't had any luck with google etc. If you have a site you like better, please post it and why you like it better. Also, if you have found a site and don't like it for some reason, would you please post that as well as I'm looking for an honest alternative. Thanks!
