All 3 of those products can do the “Matrix” effect. The Motion Emitters (all 3 sizes — small, med, large) contain the “Matrix falls” emitter.
particleIllusion SE and particleIllusion 3.0 both can load the “Matrix Falls” emitter too.
The “Motion Emitters” are just collections of particle emitter presets, while particleIllusion SE and 3.0 are standalone apps that can do MANY more effects (SE has over 1100, and 3.0 has over 1800).
