I have Home on one box and Pro on the other. Other than file encryption and some more advanced network options, I don't see much difference. I haven't had any trouble with either for last 19 months, but I would definitely go with a full install rather than upgrade. Use a minimum of 512 Ram cause XP likes it and do go to BlkViper.com to plug security holes and kill useless services.
