Can't offer advice on the two packages you mentioned, but the salon I work in installed Premier Spa in January - it's easy to use, helps ALOT with the paperwork, and the support guys are really helpful too.
We had prem spa installed in April. It has made such a difference. Call a few companies that you are interested in, and invite the reps in to demo, then you can compare. Its a big investment so its best to see a few and make the best choice for your salon.
