Release order is best because of how they redid the visuals as the games went on. Even though they're not translated I believe the GBA versions are worse than the DS ones last I recall. Also keep in mind that release order is best because they introduce new mechanics in each new game or revamp various systems so you end up with things like the Spirit Medium mechanics or petitioning the jury itself.

That guy's image is correct except Great Ace Attorney was made either in the middle or after the 3DS games, I can't remember which so you're not really meant to go in chronological order. There's also the Layton crossover which isn't canon but another PW game.
