I'm a big fan of the manga, but absolutely hated the anime. Love Hina is one of, if not my favorite manga - but I may be biased because it was my very first foray into manga.
Manga vs Anime is a lot like "the book is better than the movie" mantra. The downside of seeing the anime first is you know all the main points what is going to happen, but there was quite a bit of important dialogue left out that gives more 'body' to the story. I would do it if I were you. Just my opinion.
In addition to being produced a full year before the end of the manga, it was extremely lackluster. I'd say give the manga a chance. You won't regret it if you like comedy and romance as you say.
