I've been using Mobil 1 (locally available as Askari Gold) for 4 years now. I shifted to geniune Atlas Honda oil and Shell Helix one (respectively) but was not satisfied. Although its very difficult to quantify the performance of engine oils, but the overall smoothness and the engine note was noticably different when I shifted off of Mobil-1
Now its only Mobil-1 for my bike
