SerpIQ vs. Keyword Difficulty tool

Is this any good for keyword research? I see they use some weird metric and I'm not sure whether those are relevant at all, plus it's really hard to do a bulk research. Let me know what you think.

I have had a quick play with SerpIQ. I thought the following bits were quite interesting:

• can be used to find related terms and you can then dig down into the keyword difficulty for each keyword
• provides data on the availability of exact match domains for a keyword
• keywords can be grouped together to manage the keyword research process

I think if the first point could be automated i.e. you give it a keyword it then goes off and finds related keywords and provides difficulty scores for them it could be a lot more useful.

However, in terms of usability and usefulness I thought the SEOmoz keyword difficulty tool is far superior and won't be swapping any time soon. Some useful ideas for possible future upgrades for SEOmoz though.
