It's 167+26 episodes (original run ends at 167, final act was the conclusion that aired later for another 26).

As for if you should watch it... You could do worse. It's cheesy and predictable, but fun and has its charms and lots of that Rumiko Takahashi humor, and while the music's great, you're going to be tired of hearing it after a few seasons and it's not going anywhere. The dub is ok, the sub is decent if you prefer subs (I like it over the dub and I normally try to watch dubs over subs). There's also some filler you can dodge if you lose interest by then, and four movies to check out if you're super into the show.

If you like manga I would honestly recommend the manga over the anime.
