I have the Mastercool tool also, like it a lot, use it all the time. It creates an excellent, professional flare every time. With that said, the Eastwood tool looks a little easier / quicker to use. With it clamped in a vice you have both your hands free. It seems like I need three hands to get everything lined up well with the Master cool. Also, I think you have better feel/control with the lever on the Eastwood (if that matters).

One plus for the Mastercool, you can flare on the vehicle if room allows, done that more than a few times.

I think I'll buy the Eastwood tool someday, can't have too many tools!
