Being a user of Parallels from the start, I thought I would be excited about Parallels 3, but VMware managed to sway me over. I was getting frustrated with the performance of Parallels, and the extra cost of version 3 was icing on the cake. Sure, Parallels is a bit more polished, but it lacks on basic performance. VMware has supported 64-bit chips, dual core utilization, and DirectX since the early betas, while Parallels just now added DirectX and still lacks 64-bit and dual core support. Besides, I noticed VMware runs a heck of a lot smoother on my computer compared to Parallels.

VMware has been in the virtualization market a lot longer than Parallels, so I have a feeling when Fusion comes out of beta, it will be superior to Parallels. Although, there is no telling what could come. For the most part, Vista is still untouched by both companies, leaving Aero support up for grabs. Not to mention Apple might surprise us with a virtualization announcement at WWDC. However, I feel VMware is reigning supreme on the Mac for now and will for sometime to come.
