It's actually pretty fun, desu. Good mix of partying and cosplay, which are the reasons I attend cons. The do also seem to have a more varied selection of guests than a few other Texas cons, but I don't attend cons for guests. And there are some decent panels each year.
It's a fairly consistent good con, which I think counts for a lot in Texas. It's not like, for instance, Ikkicon or something where you're like "......how could this get more shitty?" And yet every year they manage to astound you.
Main problem with SJ lately is that it's directly opposite Dragon Con.
