Here's a few real world items that may influence your decision:
1) Polyphony is rather light. At 62 notes, you can use this up pretty quickly with layers or sequences.
2) Access to styles during seq playback is forbidden. You can locate them, but you can't change one, or have or ready when the seq is done. Same in reverse if you are in acc mode...you can't access the sequencer in live mode.
3) Sounds shut off when new ones are triggered. This is only a problem if you switch alot in the middle of a phrase, or with the sustain pedal down to free up a hand for navigational purposes. If you switch between Program and Performance mode the current sounds shuts down for a second during the switch.
4) No option to add live drum beats to a seq like Yamaha and Ketron do. I've come to love that feature. I like to "modernize" some older sequences by adding some new, hip beats to them....even a multipad adds alot.
5) Some drum fills are still a bit unconventional, and busy compared to the style. (Volumes, instruments etc .....) You may want to tweak the problem areas.
6) Effects mixer is pretty cryptic with only 4 sends. I prefer the Yamaha design where I have control over each sound's EQ, FX, Vol etc in a separate window. Nothing shared like the FX buss in the PA series.

The tone of this kb is AWESOME.
The drums samples are AWESOME.
The O/S is cumbersome, but learnable. Korg lingo takes a while to sink in, but once you "get it", you own it.
