^I'd say AP is a lot better. I mean, his ult brings you in the enemy team, which means you're going to find a lot of cc. Abilities give burst (except short cooldown abilities like Ryze's Overload and Karthus' Lay Waste), basic attacks give sustained damage. In, say, one second, abilities give a lot more damage than basic attacks. If you have five seconds, however, basic attacks give more damage. When there is a lot of cc, this will mean that you will not have five seconds, or those five seconds (for example) until your abilities are off cooldown, would count as autoattacking for 2-3 seconds.

It is indeed possible, but to me, AP feels better. Also because it's so much fun to RQE the AD carry and see him run with about 10% health, while you are chasing with your Q.
