ADIsimPLL loop filters [hlp]

Hello Everyone;
I want to use ADIsimPLL software for designing loop filter of a PLL. I want to use active filters. Which of active loop filters of ADIsimPLL library is better and more stable?

Better in what sense?

Better judge yourself by doing all posible combinations.
I believe there is no limit for more stable.
So define the cutoff for the stability and use it if acceptable.
More over you need to see the locking time settling time etc which are the same important parameters.
