I don't have any of those syncing issues with Exchange, FWIW.
As for iOS, I'm surprised by the love for it here. I hate it, but mostly because you can't attach files from the app. Yeah, you can from other apps (like going to the gallery and sharing a picture via email), but the fact you can't compose an email in the email app and attach a file to it is weird. Plus, you can't attach more than one file at all. It's very strange IMO.
That and there's an extra step to get the checkboxes that just display by default in Android. My iPad does display emails nice I suppose and it has some transitional eye candy, but I guess I'd rather have functionality. I realize there's an issue with HTML emails with Android (I'm using the default email app) but I can still pinch out and see the emails fine. Don't get me wrong, I wish they'd fix that, but it's really not a huge deal to me.
Just my two cents. When I can attach files with the iOS email app, I'll be more impressed, but that will never happen because of how iOS is designed..
