Sibenik or Split?

We actually liked Sibenik more than Split, but that may have been a function of the fact that Sibenik exceeded our expectations (we had none, so we were delighted) while Split fell short of our expectations - it was utterly mobbed and didn't seem all that great, despite the glowing descriptions we had heard. Sibenik was relatively free of crowds, no sign of a cruise ship to be found, and we really liked it. We were only there for a few hours, which seemed about right. Expect LOTS of stairs - Sibenik seemed to be one of the more vertical cities we visited.
