mild or bland nut butters?

I find all nut butters to be relatively bland except peanut butter which is why I prefer it over any other kind of nut butter. Why not just try some and see if you like any? Maybe go to a farmer's market near you. Places like that often offer samples of their wares so you may be able to try a little bit of some before having to purchase a jar of something that you may not end up liking.
