Two very different bikes, so the answer depends on what kind of riding you're actually doing.
The Kado RS is Whyte's enduro weapon: 160/150mm of travel, Bosch CX Gen 5 (100Nm, properly updated), 800Wh battery. It's built for descending confidence first, everything else second. If you're pointing it downhill regularly and want to feel planted on gnarly terrain, it earns its £5,199.
The Elyte Evo is a trail bike. Less travel, more nimble, better suited to mixed-terrain riding where you're not exclusively hunting gnarly descents. It'll feel more playful day-to-day and won't punish you on the climbs as much.
The question you need to answer honestly: what percentage of your riding is genuinely rough, techy, descending-focused? If it's more than 50%, Kado RS. If you're mostly on varied trail with the odd rowdy descent mixed in, the Elyte Evo will suit you better and you'll appreciate not lugging the extra bike around on flatter days.
What trails are you riding mostly? That'll settle it faster than any spec sheet.
