To debug my kernel-mode code, I use several VMs under VMware Workstation (now 6.0.4 but no difference since 5.5) - Windows 2000, XP (32 and 64-bit), 2003 (32-bit), Vista (32 and 64-bit). I noticed that 32-bit Vista guest works MUCH slower than all other OSes, regardless of their bitness. All other OSes, including 64-bit Vista, have good performance; 64-bit Vista is slower, of course, but 32-bit Vista is VERY slow.
Based on my experience, your last sentence is true even if you aren't using VMs.
However, I can also tell you that SP1 improves things considerably. After installing SP1, I no longer dread having to test my drivers on Vista. It's almost usable. If you haven't done so already, I strongly recommend you install SP1 on these systems.
