May not be the most relevant outlook since it's my first DP and I'm just a dabbler for now in the piano playground, but still: I picked this based on countless online reviews and opinions, the cornerstones being sound and key action (key noise also included here). These aspects are great in the Kawai (after purchase I also had the chance to briefly try Roland and Casio dp's at a local store and concluded that the Kawai stands strong against these). Key noise is somewhat noticeable even at medium volume but I gather this is common to all DP's and should not deter if you predominantly practice with headphones or at higher speaker volume (NB: headphone quality is crucial, I achieved the best sound with Shure 215, seconded by ath m50x, being somewhat miffed by the rather tinny sound of senn momentum's 3). Lastly, quick revert to key action: noticeably more responsive compared to Roland's slightly sluggish performance, which is significantly helpful for a beginner and also future proof for advanced techniques (highly recommend you take a look at pianoforever yt review to see how the main 3 contenders - kawai, yamaha, roland - in this dp category stand against each other).
