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.

ads is stronger in RF domain. It is one of the best tools of RF system and board designers. You can also use it to design chip level circuits and layout. As mentioned above, the layout tool is not so interface friendly. When dealing with large scale transistor level netlist, some time there is convergence issues.
