Don't get bogged down in the MP war! 12 MP is more than enough for 95% of peoples needs.
The D7000 is still highly regarded & at the price it is today (almost 50% of it's release price) is a bargain imho.
The best thing you can do is actually hold them in store & see which feels better to handle and see if the menus & features feel intuitive to you.
