Same. I tried to switch to iOS about a year ago, but I ended up returning the device after spending over $50 on highly-rated ad/script blockers for Safari, and finding that none of them really worked.

Back on Android, I only see ads when I visit somewhere with live TV. It's a shame, because Apple makes some great pieces of hardware, but I won't be back until they loosen up on controlling the software that I'm able to run on my devices.
