To further elaborate, getting deep into nerdland here...
The fundamental mistake with Rebirth is the literal translation. For someone to choose Rebirth over the actual hardware, they likely do not own the hardware (for those actually bothering to read this, software doesn't sound quite like 20-year-old hardware, especially in this example). Therefore, there was little reason to mimic the odd limitations of the originals unrelated to sound or performance. The UI could have been more...I can't think of the word but "homunculus" comes to mind, that is, the knobs and interactive elements could have been larger, while retaining the visual aesthetic of the originals. The 303 could have benefitted (as with modern CPU upgrades to it) live note editing. Things like that. Maintaining weird, frustrating aspects of the originals, for the sake of appealing to people who probably never owned them, would be my #1 criticism.
