London MM Investment Bank Rankings

What's the current rankings for MM firms in London; understand some strong performing American MMs have a completely different scene in the UK with some much more recently established. What would a tier list of Blair, Baird, Harris Williams, Piper Sandler, Lincoln, Stifel, Raymond James, Stephens, Cowen, DC Advisory, Arma, Canacord, Cantor and Houlihan Lokey etc look like in London? Not looking for people to say why Roths/ Jefferies/RBC / (insert bank they hate) are a MM and not a EB/large independent.
