Hi
I have spent the last few weeks looking at both of these systems and
the answer is that Final Touch wins by quite a long way but it depends what
you want to achieve.
Color Finesse is a good color corrector, 32 bit floating point, 3 point color correction with secondary. If you have ever used an Avid Symphony it is very similar to the color corrector in that with the ability to correct in a few more color spaces. The biggest problem with the current version is that it only grabs a frame so you cant look up and down the shot or timeline as you grade. Version 2 promises to address this. You also need a second app called Echo Fire to view on a monitor.
Color Finesse is kind of a plug in rather than a separate application.
CF is good and a huge improvement over the FCP color corrector but not, IMHO a serious broadcast finishing tool.
Can be used from a mouse or control surface.
Final Touch is a much more serious grading tool. You XML your sequence, close down FCP and open Final Touch and import. You must have 2 monitors.
You can grade in realtime (almost), have primary and and I think 8 secondary
color correctors. Ability to use plug ins direct into FT (look at Nattress) Motion tracking, vignettes, DVE and up to 4 grades per shot.
Used with a control surface like the Tangent 100 it really is a serious grading finishing tool that begins to look scarily like a DaVinci for much much less money.
Plus it can go up to HD and then 2K depending on what you need.
I think mouse operation may be a bit slow so really you need a control surface for real smooth operation.
Anyway hope that helps - the websites give you pretty much the features of each - I have just given very brief summary.
best wishes
