This has been discussed many times, Scott, the main reason is that the KORG keyboards are alot cheaper and you get more bang for your buck then any other brand, YAMAHA TYROS are very expensive compared to KORG, other factors are the sampling option,upgrading from a KORG PA80 to a PA1X or PA800 is better then a TYROS for most, I have always been a rebel and liked all brands, especially GEM and Technics which as I said many times were ahead of their time, but I saw that the mainstream Oriental market is KORG, so I have to buy a KORG, styles are available much easier then any other brand also, and another big factor is SUPPORT. Although here in GREECE there is no support in regards to a GREEK manual, KORG left us in the DARK, that is the biggest complaint here.
