Web Analysis Tools & Consistancy

A while back I wrote a little entry here named Comparing Web Traffic Between Different Web Analytictical Tools, where I compared Urchin 3 versus Urchin 5.5. A new thread sprung up at Cre8asite Forums named Log analysis consistancy, where Moderator Adrian discusses his experience with Weblog Expert with Net Tracker. Will there every be consistency? Only when they all merge into one company, and everyone uses the exact same analytics program and version of that program. :)
