I had both of them.
both are very loud amps, but can sound amazing room-volume, Orange is a bit dirty, has more grit to it, a bit warmer sounding. Eden has the most amazing EQ I ever heard, Orange is kind of raw in that department, it's not so effective, but on the other hand, eden's EQ is strong effective, and has a wide range of freq.
Also, Eden has an in-built studio compressor wich is really good feature
Honestly, you can't go wrong with any of them, it's just the matter of what sound do you like. If you wanna rock hard, go with Orange! If you like more cleaner, modern sound, go with eden. I personally play funk, so I was good with both of them, but ended up with markbass just because it's smaller and lighter...
