These sit in different price classes - KEF LS50 Wireless costs roughly 4.4x what KEF EGG does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | A | KEF LS50 Wireless digs deeper - 79Hz against 90Hz. |
| Built-in power | A | KEF LS50 Wireless has the bigger amplifier (230W vs 50W RMS). |
| Connections | A | KEF LS50 Wireless adds Wi-Fi and streaming. |
| Size | depends | KEF EGG is easier to place; KEF LS50 Wireless is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Ported vs Sealed. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | depends | KEF LS50 Wireless: a sub output; KEF EGG: a sub output. |
| Price | B | KEF EGG is cheaper - $499 against $2,200, about 77% less; arguably a different class. |

depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: KEF LS50 Wireless measures better, KEF EGG costs about about 4.4x the price% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 90Hz anyway, which makes the cheaper KEF EGG much easier to justify. In a large or open-plan room, KEF LS50 Wireless has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KEF EGG is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
