I've checked both these boards which you've mentioned. I would go with the metro-board just for the reason of the weight. There are many reasons except that like much better customer service, a product which is much more reliable and a more comfortable controller.
You also have much more options for customization with the metro-board like choosing different style and size of boards, different quality of wheels and different battery packs.
Also, getting the most personal technical information is something that helps a great deal. Ilan, the owner of metro-board gives exactly that!
Enjoy!
