If it's not doing frame interpolation, then how does displaying the same frame three times in a row faster make any difference?
From a purist's point of view a simple 3x frame duplication is best. Done specifically to eliminate the flicker effect one would experience if a movie was shown at 24fps. On modern film projectors the shutter speed is typically 2x or 3x the 24FPS rate. So pioneers 3x duplication to create a 72hz frame rate without interpolation is the closest to real theater. Of course if the camera pan is fast enough you will still see image judder as the information being updated is still at the films original 24fps.
This is where some manufactures have implemented frame interpolation. Using processing to make a interpolation of where the motion is headed between the 2 original frames from the source. As you can assume when we are talking about millions of pixles with various levels of luminance and saturation the processing power required can be quite demanding.
So on fast moving scenes there may be anomolies introduced that were not in the original content. Not to mention that most that have viewed this frame interpolation say it makes film look to much like video.
Again it comes down to what you like most. Heck alot of people are ok with over compressed MP3's
