yeah, i hated material ew as soon as it was announced. so much padding everywhere, and so little contrast - to paraphrase the incredibles: if everything's orange[1], nothing is. your eyes will adjust to it. i want actionable items to stand out, not be a slightly lighter shade of the same colour. it also looks rather like a fischer-price my first phone interface
i must say, if an app (for example, jerboa) uses material 3, i usually try to look for an alternative
[1] other colours are available, i just like orange
edit: some examples:
with material design, it's clear what's a header, what's a footer,[2] and what each button's state is.
with all the padding, there's also less space; leading to less functionality
with material ew, it's much harder to tell at a glance what each app is, one has to scrutinise the icon rather than just tell at a glance by colour
i also really dislike monet; the way it pulls this horrible washed out sickly pastel colour from a wallpaper and washes it over the entire app. if i just pulled one accent colour, and applied that to, say, the header and main action button, i'd like it a lot more
[2] look at the lack of contrast on that "new post" button
