I started with the standard but quickly moved to the Advanced. Why? The standard had the single aerial which meant that the picture on my iPad screen could sometimes break-up a little. No issues with the advanced. I did actually upgrade the aerial on the Standard but, again, opted for the advanced. If you like drones then you're at least set to move forward with the advanced.
Another way to look at it would be to buy the cheapest Phantom 3 you can find to see if you get along with drone flight. After that you could save, making a bigger step, towards a magical Phantom 4.
