Chebyshev filters have a faster roll-off than Butterworth filters, but they produce ripples in the passband of the frequency response. Bessel filters have a slower roll-off, and elliptic filters have both faster roll-off and ripples in the stopband, making Chebyshev the best choice for this scenario.
