I need a new blender. But not sure which one I should get. Which do you have and why do you love it? 

I have both. I have never used my Ninja (I don't have the kitchen space yet) but I understand that the Ninja is better for food processing whereas the Bullet can mix and blend and even grind things (I love it for making Fiber One crumbss) but not so much on the food processing end. Anything you blend up in the bullet needs a good deal of liquid to get it going.

I also heard the Ninja makes ice cream. In 90 seconds.

Bullet tis great, provided you don't need large quantities at one time.  in that case, you would want a full blender with a small blending jar.

I have both. Use mostly my bullet. all the time.

Bullet!

 I have both and use the magic bullet every day.  I think its because its small and easy to clean.  Doesnt' take up much space.

I have a ninja and I love it.  It blends really good, crushes ice to like shaved ice consistancy, chops, makes ice cream(soft serve).  It does other things to I just haven't tried it all out yet.

I have both. I use the bullet because I can make small, single serving shakes and then just drink out of the cup I blended in. My husband uses the ninja because he makes much bigger shakes and pours them in a large cup (not a WLS person).

I just bought my Ninja yesterday and today I fell inlove!!! Made a shaved iced peach tea snow cone! Its very easy to clean, comes with a small and large container... 39 bucks walmart!
