I say exactly the opposite is true in my case, which is why you should go to the music store and play them both so that you can see which one YOU like better. I had the 740 and PA80 together for a while, until I upgraded the 740 for the 2000. Each one has it's distinct qualities and advantages. I recently tried the 2100 out and found that the 2100 has a few added features / sounds / styles over the 2000, but is very similar to it.
My take :
PSR2100: Pros: easier OS to understand and navigate, especially coming from a 740, ( but not necessarily easier to operate in a live setting ). Good sounds overall: for my tastes superior on ac pianos, woodwinds / sax. Good styles, that work well for a variety of songs. Less expensive than PA80, basic synth sound editing features. Fully programmable multipads that can play short phrases and are dynamic and very useful. Lot's of useful aftermarket products and apps made available by users.
Cons: Poor key feel, not a very sturdy feeling piece of equipment. Drums and bass sounds are useful but bland ( for my tastes ). Not very good for detailed editing and creation of synth sounds. Harmonizer is fair but adequate for live play.
PA80: Pros: Excellent soundset overall. Detailed editing capabilities for making very good emulations of other synths or for making unique synth sounds. Styles have more life and can be useful for composing original songs. Excellent organ, drums, bass, guitars, synth pads / leads. Good electric pianos, strings brass sounds. Decent key feel. Velocity controller that can be set up to trigger fills. Very functional and intuitive pattern sequencer. Decent harmonizer, but less options for triggering chords. Multipads can be used as controllers for midi / style data. Good support / extras from users and from Korg. Any of the internal styles can be replaced by user styles. Lots of power overall to customize the board as the user sees fit.
Cons: Multipads are limited to "one shot" sounds, no phrases and no user pads. "Break" button only silences the style that is playing. Fair piano ( but can be edited ). Only 2 fills per style. Styles are a little more complex, but that isn't necessarily desirable when trying to emulate a range of cover tunes. Some fills aren't good matches for styles. OS learning curve can be difficult for a user not accustomed to it, but the board is intuitive once you learn it.
Ok there it is. If you like the styles and sounds and OS of the 740, you will probably like the 2100 too. It's a very worthwhile upgrade, as the 2000 series has much more functionality than the 740. The PA80 is a very different animal, and coming from the 740 you may not like it at all, or, like me, you may love it.
