The following are the Infinite Impulse Response versions of their Analog active counterparts, only a bit slower due to the additional bilinear transform. 3dBoct has no place here and Bessel loses it's trump card as an IIR. Hence, Butterworth, Chebyshev, InvChebyshev and Cauer are the options.
All IIRs also support the same optimizations as the Analog ones, but the results will only be relative to the lower pass-band for BP/BS.
There is also a matter of causality when sample&hold is enabled: the Analogs, when .TRAN doesn't use uic or startup, for a cosine input, the output is also a cosine, affected by the transient response; the IIRs will respond as if to a zero-offset sine input.
