Both are good, I have heard and could probably live with either. Lots of reliable information out there to help decide. I’d start with Erin’s Audio Corner on YouTube for a thorough overview of both.
I’d probably lean towards the KEFs personally being more compact and easy to handle and setup accordingly, plus the more modern aesthetics.
For reference, I currently run Vanatoo Transparent 1, KEF ls50 meta + powered sub, Sonus Faber Concerto Domus, and Ohm 5000 in different rooms concurrently .
