Hello Илья! I think that the most natural way to say what I think you re trying to say, is this: "Out of all the expressions, I agree with this one the most". Here is the breakdown: "Out of all the expressions" means that if you were to look at all the expressions available, "I agree with this one the most" means that this particular one reflects your thoughts the most. I hope that helps!

I think your question is about the use of "out of all". As your question asks what sounds natural you might find different answers from people in different parts of the English speaking world. And they might not all use perfect grammar. I think that people normally put the phrase 'out of all' at the start of the sentence, like this: "Out of all (the expressions), I agree with this expression (the most)." - they might say, or omit, the parts in brackets. Or they might use "above all" instead, like this: "I agree with this expression above all."

"I particularly agree with this expression out of all of them"

I would say: “Out of all these expressions, I particularly agree with this one.”
