Worse that Numbers and Excel.
Bluetooth keyboard support is seriously lacking, cant use arrow keys, enter key to edit a cell, and navigation in a document requires constantly tapping screen items. Lacks features that are present in the browser version, seems like app support has been an afterthought. I so wanted to like this app, but it seems like google doesnt care about it.
TLDR: App is clunky and not nearly as good as browser version. Google doesnt seem to care to fix problems.
