I do not think the US economy is doing that well as you have full employment but rather low economic growth historically. Economic GrowthRate is half under Obama then in the 80s or 90's.
Usually Presidents image over time is usually based on few things...
1. Policies and long term impacts positive and negative (Bill Clinton and Reagan Get Negatives for that).
2. Image and pop culture impact (Reagan gets a huge post in his legacy by his 'moments')
3. The President who follows them..
So the first two I think Obama does okay and the third really depends on if Hillary is a let down as if she is
