Chicken Parmesan

The recipe I'm about to use calls for marinara sauce. I have my fave spaghetti sauce. My question is: Is there really a huge difference between marinara sauce and spaghetti sauce? The spaghetti sauce I use isn't a meat sauce, it has mushrooms, onions and garlic in it. I've searched it online and the main answer I'm finding it marinara sauce is meatless and a little bit "runnier"

Marinara is watery-er, but I always use spaghetti sauce, it taste better that way. I don't think it'll make a huge difference. It should still come out the same.

we always used spaghetti sauce.
Marinara is too watery. the chicken absorbs most of it. which i dont like. blahh
