Not sure whats generating all the pop up ads. Only time I've had any are associated with certain freebie apps. They want me to buy the full version to get rid of those ads. The ads only come up when I'm running that app. If ads come up too much with that app I delete it.
As for overall usage it really depends on the person. Some prefer iOS, some prefer Android. I've used both and greatly prefer Android but then I'm a bit of a techie type that prefers the open platform OS. Plus, I can't stand iTunes!!! Much easier for me to organize and load music on my Android but again, thats just me and becomes a personal preference. Both are good in their own ways.
