Not quite correct. Even with Yahoo's free account, you can export contacts. I just did it a while ago.
I love the Gmail interface and I do think Gmail is better at Spam, so that's what I use. However, with Yahoo, you can natively sync contacts, calendar and notes just using the BB Desktop manager.
It comes down to personal preference & what works for you.
