I studied German in high school, but it didn't take. In college I studied Spanish and Portuguese, and actually the German helped a lot -not the grammar or vocab, but the experience of learning a new language was valuable, I was a better student for having had that previous experience.

Now, casually as an adult using duolingo, or listening to podcasts, attempting to read, etc, French is fairly "easy", at least the basics, having had experience with other romance languages, and revisiting German isn't so daunting either. I don't think one is "easier" than the other, but learning either is aided by what they have in common with English, although these commonalities can be a barrier to learning as well.

While learning Portuguese it was said that, if you know Spanish you get 75% of Portuguese for free, but that last 25% is more difficult to learn than for a non Spanish speaker, bc they don't have Spanish language rules interfering with learning the new language.

Having attempted to learn Swedish I can relate this in one way -its difficult for me to place definite articles at the end of words. Ex: anka = duck, ankan = The duck. In either case I want to add "the" before every noun, or, incorrectly, my brain uses "det" just so it "sounds" right, to my ear.

TLDR: I don't know if either is objectively "easier", but commonalities with your native language can also hinder learning a new language, as well as help.
