I am not sure why everyone thinks the leather loop band is plastic feeling. I tried on a blue and black medium leather loop band at the Apple Store and it felt very comfortable and I felt the leather to see what the texture felt like. The leather does have a specific pattern to it and it does have different feel to it, then say the Classic Leather Buckle. The leather still feels like leather, not plastic. I guess people think because it is not dull leather, but a little shiny, they think it looks plastic looking. If you look closely, the shine is gone. The leather itself is really nice. The Classic Leather Buckle does feel softer than the Loop, but it doesn't mean it better leather. I would have bought the Classic Leather Buckle, but with the size of my wrist, where the holes were, it was either too loose or too tight. I always have problems with most buckles because they never match my width correctly on my wrist.
I ended up getting the medium Black Leather Loop Band. The leather felt fine, not plastic. Besides, it fits really well on my wrist. It is probably the best fitting band for me. Plus, it really looks nice. My daughter and most people that were standing around all said the band looked the best on me compared to all the other bands I tried on.
Again this is my opinion, just like everyone has their own opinion. I suggest everyone that wants to buy a band for the watch go see it for yourself and make your own judgements. If you are going off the pictures, don't! The pictures are not what they really look like. Some are better looking than the picture and some are worst.
