From what I understand, resonators are less accurate, but tend to start-up / stabilize faster, which could matter in specific applications. They are often commonly manufactured with capacitors built-in; these are probably easier to "drop in" to a design and use (less fussing about finding the correctly-matching caps for the oscillator and guard rings / other layout issues). That's probably more of an issue for the very low power, low speed xtals, e.g. 32.768kHz watch crystals, but I have been bitten before by such crystals not starting up reliably using the manufacturer-recommended values, and having to stack on 1pf caps until they worked!
