It depends what you are writing for. Personally I would always use the normal word order because it is generally clearer - communication is key.

Using inversion in writing can add variety and sophistication to your prose, but it's essential to use it judiciously. Inversion involves reversing the typical word order of a sentence, usually for emphasis or stylistic effect. It's commonly used in literary and formal writing, but it can also appear in informal contexts for rhetorical emphasis or to achieve a certain tone. Inversion can indeed make writing appear more advanced due to its less common usage in everyday speech. However, using it excessively or inappropriately can also make the writing seem awkward or unnatural. It's crucial to strike a balance and use inversion where it enhances clarity or emphasizes a particular point. Regarding your example sentences: "Raining hard though/as it is, I'm going out for a walk." "Though/As it's raining hard, I'm going out for a walk." Both sentences use inversion, where the typical word order is reversed for stylistic effect. In the first sentence, "Raining hard though/as it is" is placed at the beginning of the sentence, emphasizing the adverse weather conditions. In the second sentence, the inversion is less pronounced, but it still serves to emphasize the weather conditions before stating the action. In terms of differences between declarative sentences and sentences with inversion: Declarative Sentence: A declarative sentence typically follows the subject-verb-object word order. It makes a statement or expresses an idea without posing a question or giving a command. Example: "I am going out for a walk."

Fine it is either way. "Corrected" you say you were, but by whom? Inverted word order makes you sound more refined, possibly artistic. If you do it too much though, you could sound pretentious.
