I can only offer you my experience with the 2007/8 disc since I hacked it over a year ago and it's still on my car now. I noticed no routing bugs or glitches here in SoCal, and I use the satnav daily for business. I get the feeling that, by hacking the disc, as an unintentional bonus you also avoid introducing the routing bugs reported on the 2007/8 version!
All you gain by hacking the DVD is updated maps and POIs, while the interface and - I assume - routing calculation "logic" remain unchanged. It's when you run the loading.kwi file that the interface and routing speed improvements of the later discs are implemented in the system, possibly along with the bugs reported... Just my guess, though.
