I know it isn't finished, but so far I like the old one better. The new UI is just so cluttered and tries to display too much information in too small a space. What I like about the old UI is it is bright, straightforward, well organized, information is displayed in consistent places across screens and the screens are divided up so everything has enough space to do its job. The new UI is dark, the information displays are smaller, oddly shaped or place and some things are placed where they really don't belong.
