Gyakuten Saiban (not the Anthology Comics) and Monster Hunter Orage.
The first is a nice add-on to the Ace Attorney games, with their own cases. They're also easy to get into for people not familiar with the series. But fans will get the most out of it.
The second, you can totally see who the author is. As with the other series from Mashima Hiro, you can see a lot of similarities. But an enjoyable series nontheless. The art is really good and the battles are beautifully executed. Just as with the first, you don't need to be familair with the series to pick it up.
