Some people wonder if AMS Designer is less accurate than Spectre. It is not. AMS Designer employs Spectre underneath, so you can expect similar behavior and accuracy.
If you system is entirely analog, then Andrew is right, using Spectre is generally best. It is a cheaper license, and you get a much wider palette of analysis choices (AMS Designer is largely constrained to transient analysis).
However, if you are simulating a mixed-signal system, it is generally much easier to write mixed-signal models in Verilog-AMS, and they can run much faster.
