I think KWG is inherently more valuable though. I'm sure that if there is background accumulation, that it will be a bit of a wash between the two.
I wonder if someone with more familiarity with the background issues of the two companies could post a detailed comparison of SPQ and KWG. To be honest, I've been out of them since 2008, and only recently got back in with a small purchase (of KWG). I did well with SPQ in 2008 when it went from around 8 cents to 15.5 and I got out then before things settled back down.
The similarities between the two companies are striking, in an overall sense, but there are many differences too.
