The MacFormat review was for Parallels Desktop 5 and VMware Fusion 3. I guess it shws how people's opinions vary. The conclusion to their three page review is:
If much of this review sounds like we've reviewed the same app twice, that's because, to some extent, we have. In their efforts to better their rivals, VMware Fusion and Parallels Desktop have ended up becoming rather similar. Even one of the features Parallels boasts about regarding version 5 of its app - the ability to copy and paste styled text across systems - appears present and correct in VMware Fusion. Therefore, the best virtualisation product to buy largely rests on whether you would prefer the speed of Parallels Desktop over the more refined, polished and Mac-like experience offered by VMware Fusion.
For our money, Parallels Desktop's extra speed perhaps affords it the edge by the slimmest of margins, but objectively this race is now a dead heat - both are impressive and even their shortcomings aren't major. As such, we no longer recommend that anyone using one product should switch to the other - stick with what you know and upgrade to the latest version.
Parallels Desktop
Four stars out of five
"Fast with good graphics support, but a little awkward and intrusive."
VMware Fusion
Four stars out of five
"Polished and highly usable, but slightly slower than its rival."
