I have both and so far I find three things that the SE has over the F75.
The TID on the SE may be slightly better, after you learn to read it. However the F75 TID is much easier to use, it beeps and show's a number while the SE beeps and you have to get the threshold tone back before you get the crosshairs or numbers. Once you get the threshold back, you have more info, once you get it back...
The build quality is better on the SE.
The tones are more pleasing to the ear on the SE.
So far those are the only things that I can find that are better on the SE. I have not been able to compare depth or ID at depth yet and this is what will make the difference to me, if in fact the SE is better at depth.
