A lot of folks didn't quite understand that you want a better acoustic guitar, but are also wanting to by an electric guitar.
It's not really the guitar holding you back. More likely it is what you are trying to learn and how you are trying to learn it. Without lessons from a human, you cannot reach full potential. Videos and books cannot answer questions or show you if you are doing something wrong.
I learned quite a bit on some REALLY bad guitars, but did take just a few lessons and practiced a lot.
So consider that.
As far as a new guitar goes, a lot depends on your budget and what you are looking for as an improvement.
If it is just the action of the guitar, try changing your string gauge first. Those cheap guitars can come with stiff strings. If you get thinner strings, you can do more with fingerings and chords, since some chords are tough to play with a stiff guitar. Try putting on some Extra light gauge strings first and see if it helps you.
If you are looking for a $250-400 guitar, then check out fancier Yamahas, Ovation, Ibanez.
I like Ovations personally.
Ask later about a solid body electric when you know what you are trying to do with one specifically
