You feeling ok?
Lets look at this with facts and look at this from an open perspective.
On one side we have Apple, who have little to know experience with maps, and who had to purchase a mapping company to get into the market.
On the other side we have Google, who have been producing maps for over 7 years, and again have been producing, and working on 3d mapping technology for at least 7 years. Google have obviously been playing around with 3d mapping for a hell of a lot longer than Apple, and have a more experienced team working on it.
Sorry, but no matter how much of a Google or Apple fan anyone may be, facts are facts. The statistics say that Google will provide a better service than Apple here.
Lets also look at how it works. The maps are fed by a cloud network. Google obviously have one of these. Apple does not, Apple has a single datacenter (note: A true cloud has servers all over the world, not just in one location). For international users Google Maps will obviously run much, much faster (assuming Apple dont use an existing 3rd party global cloud instead of their own facility). On top of this, Apple's experience with online services isn't exactly good. The entire network regularly experiences massive slowdowns and was even crippled when they launched iCloud with most not being able to access any Apple online services for several hours.
Now, I'm not saying that'll happen, but if they dont start investing serious money into MULTIPLE facilities all over the world, they wont get anywhere.
Am I an Apple 'fan-boy'? No.
Am I a Google 'fan-boy'? No.
I use products by both companies every single day, I have no 'love' or commitment to either, they provide what I need to get my work done, and that's all. If something better came along, I'd use that.
