The new logo looks like rubbish to me. The old logo had symmetry and a sort of yin-yang motif. I can't think of anything good to say about the new logo.
The best logo I've come across is the FedEx logo: simple, elegant and it has an easter egg in it. It wasn't until I noticed the hidden design in the logo that it became my all time favorite. Look at the E-X part to find the easter egg.
