You're making the Sony out to be lacking AF speed, but isn't this model rated as one of the very fastest?

It is not rated, but claimed by Sony to be one of the very fastest, under specific usage conditions. We haven't seen an exhaustive review on the A6000 yet to validate that claim.  Sony's ads, and the early use reports that I've so far seen, display tracking AF with predictably moving subjects like cars and dogs running towards the camera.  None with erratically moving birds in flight, or where one is attempting to track an eye in a complex field where some depth and color discrimination is required...or in rather dim lighting conditions.

Current DSLRs with dedicated PDAF sensor subsystems can do all these things rather easily and reliably, and it's a big reason why skepticism runs high when claims of equivalent performance are made. On-sensor PDAF systems can do a lot of what dedicated systems can do, and, because they work directly off the sensor, can focus with more precision. However, the only system that can focus accurately and reliably on erratically moving targets as well as, and sometimes better than, dedicated PDAF systems has been Nikon's Series 1 - and those cameras switch over to CDAF at fairly high light levels, EV 7 or 8 (bright interiors or open shade) as compared to the EV -1 to -3 of dedicated PDAF systems.

There are some technical reasons why on-sensor PDAF may have a hard time equalling dedicated PDAF system performance under ALL conditions, particularly low-light, which I won't get into here. But for most intents and purposes the A6000's AF performance appears to be quite impressive and giving Series 1 a run for its money.
