So far, I like this achievement list the best. It has direct URLs so you can bookmark/show off the list, and plenty of stats.

That's about all I've found so far.
I bought 4 Xbox Live Arcade games so far, and I grabbed Fable and Lego Star Wars for the Xbox1 the other day. I even ordered the Vision camera pack, which includes 12 month Live Gold, 3 games, and 200 points. That should be in this week sometime.
