Styles, or no styles
Do you want a band behind you, or a piano in front of you?
Casio states there is no auto-accompaniment on the CT-S1. Yamaha builds the PSR-E383 around 260 styles. Neither is a compromise of the other.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
Take the CT-S1 if the goal is piano playing and the styles would only ever be a distraction. Sixty-one curated sounds, a published weight of 4.5 kg (9.9 lb), and the adapter in the box.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Take the PSR-E383 to play whole songs from the first week. Smart Chord and 260 styles keep a beginner playing music rather than exercises, and Yamaha publishes its polyphony, which nothing else here does.
It is a different instrument. Casio spent the space on the sound engine and the speakers instead. If you never use accompaniment — and many piano learners do not — the absence costs you nothing.
How many notes can sound at once, including notes still ringing under sustain and every note the accompaniment plays. Forty-eight is comfortable for this repertoire, and Yamaha is unusual in publishing the figure at all.
61 touch-sensitive keys · 61 sounds · no auto-accompaniment
A keyboard built like a piano rather than like an arranger: 61 touch-sensitive keys, 61 sounds, and deliberately no accompaniment styles. Music rest and power adapter are included; the pedal is not.
Best for: Someone who wants piano sounds and 61 keys without an arranger’s menus.
