Electrolytic capacitors will generally have a higher ESR than ceramic ones, and in a switch-mode supply, ESR is probably the most important parameter.
Electrolytic capacitors age with time and heat, and the ESR can make them heat up with high ripple currents.
The capacitance of ceramic capacitors (other than COG ones) reduces as the voltage on them increases. At their rated voltage the capacitance will often be a lot less, maybe only 30% or so of the rated capacitance. Having physically larger ones often reduces this effect. However the ESR is usually what makes most difference so the reduction in capacitance may not be important.
Ceramic capacitors can crack if there is any flexing of the board.
