Comparing English to Latin is not like comparing the Sistine Chapel with a sketch. It's more like comparing the Sistine Chapel with a modernist painting.
Is the Sistine Chapel objectively more beautiful than Mondrian's Broadway Boogie-Woogie?
That’s still a bit dubious IMO as it implies that Latin is the way it is because it reflects an older, “classical” style.
Which is not true at all (ask any historical linguist) and only appears to be true if you restrict yourself to looking at Western European language.
But in reality, there are ancient analytic/isolating languages (e.g., Classical Chinese), and contemporary highly fusional ones (e.g. Finnish, Navajo).
