A lot of engineers don't have much confidence in ads's timedomain simulation. If you trust Agilent, and you think they provide good algorithms for both HB and transient, then you can use ads for your IF circuits.
Though, ads's HB is very powerful, fast with acceptable accuracy if you are handy with it.
