jit.p VS own matrices for pos + vel + whatever for particles ?

Hi there,
and again big up for MIRA & 6.1.3 !

exploring potential & expressive power of particles system, I'd like to know your opinion (and facts) about the use of jit.p family of objects VS own matrices.

I studied at least 3 ways to go with particles in Max6:
- jit.p family
- own matrices (position + velocities + jit.gen for all stuff) then jit.gl.mesh drawing points
- floating point texture and moving every calculations on the GPU (through jit.gl.pix or slab + shader)

I didn't test the last item yet.

Of course, everything depends on:
- particles particles interaction or not (collision detection, flocking etc)
- forces applied (rotational, gravitational etc)

What are your experiences and feelings about this ?

I used to make my own matrices etc, but jit.p seems really nice.
