I've never played a Takamini, but I hear good things about takamine guitars, so probably no worries. However, it is only a 3/4 size guitar - if you have big hands like me, that might make things a little difficult.
You'll find that the string tension on the epiphone will be lighter, and playing in general will be easier on the fretting hand fingers. It might benefit you to try the same chords on the electric and see how you get on. A G7 on the epiphone might be a breeze for you.
Bottom line - does the music you want to play work best electric or acoustic? I learned classical originally, and didn't get an electric until 8 years later... but now electric is pretty much all I play.
