I'd say that in this case I'd give more credibility to someone who follows logical punctuation, as long as they followed it consistently. I prefer it both logically and aesthetically, and, perhaps because of this bias, would wonder if someone following the "periods and commas inside the quotes" rule is just mindlessly following a rule. Language evolves over time, and in my opinion logical punctuation has become common enough to be a credible choice. Most people these days take the "do not end sentences with a preposition" rule with a grain of salt, and I think that the MLA method of quoting is headed in a similar direction.
