Hmm,. sounds a bit Tolopsian to me. ;)
I stand by what I said in the other thread, there is no such thing as "the best", they all have different features and different people will prefer different boxes for different reasons, also, most people will probably have only tried one type of box, at the most two. Do some reading, decide what you want out of the box in the first place, blanket questions will only receive vague answers.
PS. Schoolboy attitude will not get you very far on this forum and similarly in life . ;)
PPS. If you want to know which has the fastest processor look at the individual specs, they are all pretty similar with capability, as they all use Linux as a base.
