I like multiple app stores, and multiple vendors to buy apps from. I like downloading program source and building an apk from it. I like having a terminal app and a file manager. I like running an ssh server to get files on/off the phone. I like using the phone as an oversized USB flash drive, and not having to install a vendor's software to do it (and not caring which OS I'm booted into at the time).

iOS is pretty, well-thought-out, performant, predictable, and the best ecosystem on it isn't produced by a tarted-up advertising firm. It has a lot to recommend it...but I'll still take the tangled nest of features over the carefully pruned garden, because I don't always agree with the decisions of the gardener, and I like to have other options.
