For music, the only option is iPad. Audio latency is still an ugly thing on all other tablets, and devs and music technologists have embraced the platform because of how singular it is, as compared to the fractured state of Android. There are like three different iPd specs to design for, compared to something like 5,000 different Android specs globally.
For everything else and generally daily use, it doesn't matter, and your probably be better off with an Android.
