Gmail does better than most alternatives for antispam. It's pretty good for deliverability (although it's actually kind of bad for receiving mail from semi-sketchy places; it doesn't even go into my spam box).
It's a slow UI (I often see 20-30 second page loading times on a fast network, over SSL), the support on the free tier is horrible (i.e. non-existent), the $50/user/yr support is below what I'd want for a company to rely on it (it's ok as second or third tier support for your in-house people, I guess, but not great frontline support for non-technical users when traveling).
The real killer, though, is lack of the enhanced features Exchange offers for directory, scheduling, etc. I always hated people who depended on those kind of things, but once I started using them, it made life annoying to not have them. Google Calendar and Google Contacts are feature-incomplete and often buggy (syncing to devices, other than maybe Android phones), especially when you have multiple calendars, sharing, etc.
It's all fine for individual users, but for a group of 5-25+ people (startup, pe fund, etc.), using google apps often sucks.
