Does anyone actually trust the SKCA keyword results?

I thought this would be pretty much an ideal tool for saving a shitload of time on keyword research. In theory, you just do a little brainstorming, scrape a bunch of keywords from a few pertinent websites and Google Keyword Tool, then dump the csv into Stealth Keyword Competition Analyzer, and take care of other stuff for (quite) a few hours.

Problem is, Market Samurai and Traffic Travis paint a much different competition picture for many of the keywords SKCA labels as "Awesome" or "Great."

I am thinking of getting a refund.

Anyone here credit SKCA as an integral part of some top Google rankings they've attained?

Seems some swear by it like the chaps behind "Content Revenge".

I haven't tried it but considering the tools I have used before, you have to take it with a grain of salt. Even Google's keyword tool give inaccurate info because it includes Google partner sites and possibly other sites using adsense into account. You kinda have to take all these results with a gain of salt, IMO. More or less and indicator. Hard to say what factors SKCA is taking into account.

Well all I know is that Market Samurai is way off. This one seems kosher...

Whats the most accurate tool to use that has been tested to rank for the keyword
with what the keyword tool says.

I just love Josh's Keyword Scout,

I do not use any other tool.
