OK here is the verdict...Walnuts are better. I used the almonds and I also put in peanut butter chips. Now as far as nuts go, almonds are one of my favorites and walnuts are close to the bottom of my nut list. Don't get me wrong, I do like walnuts, but compared to all other nuts they just are not my favorite. In banana bread though, the walnuts work much better for me. The almonds were good, but the flavors did not compliment each other as well as I had hoped. The big surprise for me though was that I liked it better without the peanut butter chips too. They were a bit over powering. I did use a lot of chips so maybe if I cut the amount down it would be better, but I think next time I will use walnuts and not chips.
While it was baking though, my wife was in heaven. She stayed near the kitchen to just smell it. She said it was the best smell ever

And that is coming from a pregnant lady who has had a lot of trouble with smells during her pregnancy.
