I can not say for sure because I have only used the RS 49-425.  The only other PIR I am familure with is the Regent MS20.  Both seem to work well based on information here.  I picked the RS PIR due to size.  "Smaller is better" at least I keep telling myself that.  .  I think the Regent may be a little more stable in the elements of the outdoors.  And the Regent may have a longer field of fiew than the RS PIR.  Other than that I can't tell you much more, but maybe some who has used both can.
