Short answer: both are discontinued, and they are rated the same for sound quality (#25 and #23 of 226 floorstanding speakers). Either one is only an option used, so choose on condition and price. If you want one new, the KEF Reference 5 Meta replaces the KEF Reference 5 and is rated 4.8/5 at $49,999.96.
The case for the KEF Reference 3: The 2014 Reference generation between the KEF Reference 203 and the KEF Reference 3 Meta, a three-way floorstander with a Uni-Q midrange and tweeter, two 6.5” aluminum woofers, aluminum-skinned baffles and flexible port tubes. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
The case for the KEF Reference 5: A tall three-way tower with KEF’s Uni-Q array, a 1” aluminium tweeter inside a 5” aluminium midrange, between four 6.5” aluminium woofers, plus interchangeable port tubes to tune the bass to the room. The catch: KEF’s data is not reliable below 200Hz, so it has no preference score; the rating is estimated from it and the KEF Reference 5 Meta that replaced it.
Buy the KEF Reference 3 or the KEF Reference 5, whichever you find used in better condition; both are discontinued. For a new speaker, buy the KEF Reference 5 Meta, which replaces the KEF Reference 5.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: KEF Reference 3 4.4 to 4.8; KEF Reference 5 4.3 to 4.9). Treat this verdict as provisional.

Newer model: the KEF Reference 3 Meta, ranked higher, rated 4.6/5.
Older model: the KEF Reference 203 (ranked higher, rated 4.6/5). See every KEF Reference generation.
Pros: The 2014 Reference generation between the KEF Reference 203 and the KEF Reference 3 Meta, a three-way floorstander with a Uni-Q midrange and tweeter, two 6.5” aluminum woofers, aluminum-skinned baffles and flexible port tubes. SoundStage named it a Recommended Reference Component for strict neutrality, high resolution and deep, extended bass.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. At 51.3 kg per speaker it is heavy, and it has been replaced by the Meta version. Discontinued.
