A brief analysis of Gal 2:20 translations

According to the Bible Gateway, there are sixty-two English translations of Gal 2:20, and 49 out of them show the objective genitive translation of the Pistis phrase: "by faith in the Son of God." Only 13 of them, as in the table below, have the subjective genitive translation: "by the faith of the Son of God." Among these 13, two of them (see "red" color below in the table) translate the preposition "en" as "in or within." The other noticeable thing is the NEB translates the preposition as "because of." Some translations emphasize the adjectival form of the noun "faithfulness" in place of the simple noun "faith." What do you think is the best translation?
