Synchronous requires you to wait around for your "slot", plus
introduction of extra bit-times on the wire for timing. Anynchronous
avoids this at the cost of less delay in start of transmission, but you
must insert your own timing signals (preamble). ATM gets a bit tricky
to synchronize at high speed where accurate clocking is critical.
Dealing with ATM itself versus Synchronous Serial (SNA, BSC, etc) you
also have fixed frame (cell) sizes to contend with.
Note that traditional T1-T3-etc circuits are essentially synchronous as
timing is provided by the network.
