Carnot is more efficient.

Cornot cycle is more efficient than sterling cycle.

But the question is asked in a general case. So the answer should be less than, right?

Only when regeration is employed. If the heat rejection during constant volume process is consumed wholly in the heat addition (also const. Vol) process, needless to mention, both being reversible, then the area under heat rejection curve and that for heat addition curve are congruous. This will give the efficiency [1-(T2/T1)]. T2 the lowest temp of the cycle and T1 the highest one.

The efficiency of the Stirling cycle is as same as the Carnot cycle efficiency.
Practically it is not that easy to build a Heat Exchanger to operate continuously at that much high temperatures. This is the major difficulty in the Stirling Engines. So these became obsolete after the introduction of an Otto cycle and the diesel Cycles.

Due to heat transfer at constant volume processes, the efficiency of the Stirling cycle is less than that of the Carnot cycle. But the regenerative Stirling cycle has the same efficiency as the Carnot cycle.

What is stirling cycle?

For regenerative cycle efficiency of carnot cycle = efficiency of stirling cycle.

If regenarator is used then the efficiency of stirling cycle is equal to carnot cycle otherwise the efficiency is less.

The efficiency of Stirling cycle is equal to Carnot cycle. This is due to the fact that the cycle is reversible and all reversible cycles have the same efficiency.
Ex: Carnot, Stirling, Ericsson.
