If it's for company use I'd say go with Google. The main drawback to Apps accounts are being unable to use Google's newest toys as they come out (or sometimes ever). The upside is best of breed spam protection, great email tools, and one of the best online office suites available. And for $5/month per person it's well worth it to pay the money and forget about it. I have tried Fastmail in the past for personal usage and was happy with it. I wish I'd have stayed with them for that particular use case, but alas.
