I'll throw my 2 cents. Do the number of apps even matter for day to day use? On my G. Nexus, I only have a handful of apps that I use day to day and a game or 2 to play when I am bored. Sure having a greater variety is nice, but at the end of the day you will only be using a handful. In the end, the essential apps will make its way to the Windows Store.
In the end of the day you have to ask yourself what I am going to use the tablet for. If you are going to play games on it, then the iPad is your bet. Browsing and reading is probably another iPad specialty thanks to its high dpi screen. But being productive is something definitely suited for Surface. Personally, I am buying the Surface since a breath of fresh air. I just hope a proper MKV player gets released for it soon
