Which is better for a beginner?

The Casio PX-S1100 is the easier buy at $599.99, and its 5 touch levels and textured keys help a beginner. The Kawai ES120 is the better long-term pick if the student will use sustain, sostenuto, and soft pedals.

Is the Kawai ES120 worth the extra $161?

Yes if you need three pedals and half-pedal control without buying add-ons. No if you mainly want a slim, light piano for casual playing.

Which is more portable?

The Casio. It weighs 11.2 kg without batteries and can run on batteries, so it works without a power outlet. The Kawai is compact but listed as manual power only.

Do both have Bluetooth?

Yes, but differently. The Kawai has Bluetooth built in. The Casio uses the included WU-BT10 adapter for Bluetooth Audio and MIDI.

Which has more sounds?

The Casio lists 18 tones, including a German grand with string and damper resonance. The Kawai listing only states polyphonic sound without a tone count.

Both are plastic-bodied digital pianos with weighted actions and no published lifespan figure. The Kawai's included three-pedal unit saves wear on add-on pedals; the Casio's battery option adds a part that can wear out.
