Time remapping or Twixtor?

Also, there seems to be less frame blurring in the Twixtor demo piece then with Time remapping. What would the best settings be with my HVX 200 if I was going to be slowing down and speeding up the footage with ramps like this?
 
It also seems that the twixtor plug in is available for FCP without having to use another program. How then does Twixtor defer from the Time Remapping tool?
 
I haven't used twixtor since OS9 but it does a completely different and much better job than the Time Remapping tool in FCP. Apple should have bought the Twixtor plugin and included it in FCP instead of creating the Time Remap tool.
Like I said, It's been awhile but Twixtor actually creates frames in between the frames taped in camera. It's in a class by itself. Unfortunately it's pricey

Twixtor vs FCP

Final Cut just does basic frame blending - blending frames at varying opacities to make new frames - no content within the frames is changed. Exactly like taking stills in Photoshop, putting them on top of each other, and adjustingthe opacity percentage. Content within the source frames isn't changed at all.

Twixtor is an entirely different (and MUCH slower) beast - it examines the frames on a pixel for pixel level, and assigns motion vectors to each pixel based on what has changed from the previous frame. So the new frames can be completely different from the frames they were created from (on a pixel for pixel basis). Yeah, I'm getting a better analogy now:

Twixtor interpolates PIXELS from the frames over time to create brand new frames, FCP blends FRAMES to make new frames.

Twixtor is better but verrrrrrry slow. Occassionallly gets weird spikes if the motion is complicated, but those can be painted out/painted over with After Effects.

Shake's Optical Flow stuff also does gorgeous pixel vector based time remapping.

I've been using Twixtor to interpolate smooth motion at 24P from rotoscoped animations done at 12P, so that it almost looks like normal 24P movement, instead of the normal strobing of tripling 8P or doubling 12P. It does generate "splatter" frames, which I'm actually leaving in due to the type of look I'm aiming for (not cartoony - rather like a painterly realism). It does an outstanding job of straight slo mo, but again, it is dependent on your source. It can be guided by a reference source, which does help avoid the "splatters" to a certain extent.
