Honestly, I used to use CV-to-VCV and Hiragana-to-Romaji plugins, but that was back before I started tuning each individual note manually. Now that I do that, I see no reason to use CV-to-VCV and Hiragana-to-Romaji plugins since I'm tuning each individual note manually anyway.
Though I do currently use autoCVVC since CV/VCV to CVVC is just a major pain, even when I'm tuning each individual note manually.
