In my opinion, the XXL540 is a better choice than the VIA1535 unless you place high importance on some feature that the VIA1535 has which may not be present on the XXL540. For example, I have a GO LIVE 1535 that has Bluetooth connectivity to my cell phone. If it were not for that feature, I would prefer my XXL540TM to my GO LIVE 1535, especially given the price difference.
FWIW, the recent prices for the different versions of the XXL540 have often been very, very close to the same. If you can find a XXL540TM for almost the same price as the XXL540M, I think that it would be worth the difference - although I would not pay much of a premium. My experience has been that there are occasions when the Traffic report has been a real convenience. They have not been frequent, and I would not pay a lot extra for Traffic, but they have occurred often enough to be worth today's small price differences between the XXL540M and the XXL540TM.
Since it's running a 266MHz processor instead of 400MHz, it's not quite as snappy as the list you mentioned, but it's a WHOLE lot better than any of the recent designs... much closer to the old speed than the new.
