Short answer: the KEF Reference 5 Meta. Both are rated 4.8/5 for sound quality (#6 and #5 of 226 floorstanding speakers), and the KEF Reference 5 Meta costs $49,999.96 against $224,999.98 for the KEF MUON, with sound quality a draw, the lower price decides it.
The case for the KEF MUON: Ultra-exclusive sculptural 4-way floorstander crafted from super-formed 6mm polished aluminum, designed by Ross Lovegrove. The catch: Monumental 2-meter height and 253.5 lbs (115 kg) weight each, strictly made-to-order at a luxury collector price of $225,000 per pair.
What the KEF Reference 5 Meta does well: Flagship 3-way floorstanding tower of the Reference line. The tradeoff: Weighs 132.7 lbs (60.2 kg) each and stands 1.35 meters tall, requiring dedicated high-power amplification and substantial room space away from corners for optimal imaging.
Buy the KEF Reference 5 Meta. Both are rated the same for sound quality, and it costs $175,000.02 less than the KEF MUON.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: KEF MUON 4.5 to 5.0; KEF Reference 5 Meta 4.6 to 5.0). Treat this verdict as provisional.
