I'd prefer Xoom or some other Android tablet.
Spec for Spec
Xoom comes out on top overall. It has better cameras (front and back), better resolution, at least twice the RAM (apple hasn't confirmed RAM in iPad2 yet, but most think it'll have 512 or 256; Xoom has 1GB), standardized connections (means their cheaper to buy), few extra sensors, expandable memory, and first OS in market actually built for a tablet form (iPads is really just an scaled phone OS).
However, iPad has better overall market experience, lower initial cost when you consider the 16GB models, ... easier syncing with iTunes (however, I prefer the drag/drop method than auto sync of my media and I hate iTunes). More total apps (however, if you want something there is probably an app there for it on either system).
Additionally, the new Sony games stuff and the Tegra2 processor will have a probable bigger game centric library in a year on Android tablets.
Personally, I'm waiting for xmas time when there are tons of Honeycomb based tablets out with various sale prices. I should be able to get a Xoom level (or better) tablet with 32GB at least for cheaper than iPads 16GB model easily then.
