Baseball has roughly as much "density" of events as a game of ODI cricket, but it lasts about half as long. If that sounds like your cup of tea, then it's an interesting take on the classic wood on leather, and certainly could be worth your time.
However, it is massively in favor of ball over bat, so don't feel too disappointed if that absolute ecstasy of a middle of the bat gunshot sounding home run ball doesn't happen as often as you were hoping. There's still a lot to the game besides that, and in particular I think the clockworkesque precision of the fielding on 9/10 plays where the ball is put in the field is an absolute wonder to behold.
So tl;dr, it's definitely worth it as a change of pace, and the MLB playoffs in particular can be particularly exciting. However, I'd say it's a solid step below Test cricket in particular with regards to the variety, and strategic depth the game has to offer.
