The Ocho was a bad-assed ride, no doubt. Good radar, great de-ice, sorta-kinda FMS (actually just a spiffy RNAV box), good autopilot, APU, FA, really quiet....just air conditioning that blew large chunks and the climb rate really petered out above 14k. The later model -100s with the improved cockpit ventilation were marginally better on the AC. The -200s were all around much better. Much better climb & cruise performance and air conditioning that actually worked. They had UNS-1B GPS based FMSes, but to be fair, they didn't really add any functionality over the KNS660 RNAVs.
The experience that was USAir Group at the time was another matter entirely.
