I love them both and have fallen WAY behind on both but Bleach takes the win from me I can deal with its filler much better.

I haven't watched either very much but I've seen more Bleach. I did my college senior research project on Japanese anime and American cartoons. When I started my research I had to choose my anime. One of the ones I looked at was Naruto. I watched up to about episode 5 and I was fully uninterested in it. I'd like to actually watch Bleach. I've only seen several episodes at my friend's house on adult swim.
