Text will always make JP the fastest for every category in SS, unless you're doing something like Ancient Cistern IL

Yes. Text speed makes JP faster than USA 1.0 in every case except a TAS (where the text speed is ignored for region/version comparisons insofar as TASVideos is concerned- the JP TAS would be faster timewise but slower gameplaywise) and Ancient Cistern IL's. Otherwise JP beats USA 1.0.
