I enjoyed both of these. The writer is making a genuine effort with the personas, Ryoga and Ranma are both in perfect character, their mutual feuding/bickering is hilarious, there are plenty of gags, the battle sequences are great, and one of the villains (Jadeite) is a quite insightful/realistic rendition of a real world-style Complete Monster
. It also helps that Rowan himself reads as a genuinely nice person, which makes the story more enjoyable. The ending left me with conflicting feelings, but that's a comparatively very minor detail.
