Why use it? because MMF would probably just confuse a complete noob.
The differences are HUGE in it, yes there are same editors but the GUI is way different, theres only about a HUNDRED more buttons or so everywhere, lots of sub-windows and toolbars. a complete noob would get completely lost in MMF, while TGF there isnt as much buttons all over the place, less toolbars and its simplified.
Im not saying TGF is better then MMF, but for a noob its alot better.
And remember if he does get TGF and wants something more powerful there is always that nice shiny discount you get off MMF
I don't see what's wrong with using MMF if you're a noob. The only problem I can see with it is finding some of the features available in the Picture Editor which are tucked away in menus and vertical toolbars - and that's not a big problem if you use PS(P) for your graphic.
Learning TGF doesnt make learning the software easier, it's just learning a different piece of software that you find easier because that's what you learned first.
If you start with MMF you'll find it just as easy to learn than if you started with TGF... The only difference being that MMF is more powerful and more current, so it's better to learn MMF from the start anyway.
