Both ML and Tannoy make very good speakers. What sounds best to you, only you can determine.
I own a pair of ML Spires.
ML speakers require both space and power to sound their best. They are capable of going down to 1Ω which can blow up a lot of amps. They are rated for 20 - 500W.
I drive mine with a pair of 900W monoblocks, fed by a tube preamp. I couldn't imagine trying to drive them with a 50W amp even though, technically, ML says they are rated for that..
I also have tube monoblocks that produce 75W. The ML's sound more musical than the SS amps on some types of music (e.g. jazz, big band, instrumental) but the tube amps definitely lack the slam of the SS amps.
This audio obsession of ours is a funny business. We can discuss measurements obtained from different audio components and systems, but in the end, we cannot measure how we process that stimuli in our heads.
In the end, as long as YOU enjoy the music, that's all that really matters.
Stay safe.
