TassinFlat (and all Picture Controls) adjusts how the camera interprets the video it captures as far as the tone curve. Since video isn't RAW on these cameras, the image is pretty much "baked in", meaning you can't recover much in the way of shadows or highlights as you can with RAW videos/images. These Picture Controls alter the tone curve to capture as much detail at the extreme ends as possible at the start. Then you correct the curve in post to make it look normal again. You'll have more detail in the shadows and highlights, and you can keep or clip them as you please, instead of working around them.
5DtoRGB is more of a video clean up/converter tool, and is used as the first step before any editing is done. It will reduce the blockiness caused by compression, and allow you to output video to more video-editor-friendly codecs. Some versions also have an option where you can correct the tone curve from a flat Picture Control, though doing it in an editor during grading would make more sense/give greater control.
