No, it's objective. I am fluent in 3 human languages and studied linguistics. It is simple fact that English is less complex grammatically than Latin languages, you can't refute the simplest of points, for example conjugation

In Italian the word "fu" is a sentence in and of itself that in English translates to "in the distance past, it was" English basically doesn't have that verb tense, nor does it have agreement with the subject in the conjugation. I believe in Latin theres is an even more complex layer where the gender of the subject is also accounted for in the verb Conjugation. This is proof of the simplicity of English.
