As a counterpoint, I would like to note that Lucario has only existed since 2.1, and only really been stable since 2.6b, and due to this, is vastly unexplored. We know Lucario's got a crazy punish game, has trouble in neutral, and has hard matchups with characters that have and use solid zoning options, and that is primarily due to the nature of his design that this is known. Fox is good because, as you said, all of his options are good, which is why we consider his Neutral to be one of the best in the game. But there has been an unimaginable amount of time put into learning not only what Fox's moves can do, but also when an when not to use them. His neutral is the best because we know how and what options to use.
Lucario, on the other hand, has... maybe a year of relevant metagame development, and while there have been quite a few noteworthy players that have picked him up for a short while to try him out or have some fun, in my opinion there is not solid representation for the Steel-Fighting type at this time, which means that the folks who know the game exceedingly well, those that could significantly accelerate the learning of the character's intricacies, are... well, not.
At this time, I would say that Lucario is seated pretty firmly in the middle of... well, pick a tier list (since right now all of that is kind of silly due to lack of data). There is potential for him to improve, but it will take quite a bit of time and effort.

To my knowledge, Uthrow chains only work on poor DI. If a FF DIs correctly, they will be forced to tech. If you are looking for chain throws, you will have to use tech chases. Also, fun Lucario combo for a spacie: at 0% uthrow(poor/noDI)>usmash(3rd)>aFP>dair(1st)>aFP>tech chase, which should push his damage to the point that they will tumble from utilt (which is important for combo safety).The thing is Lucario can 0-death Fox, he's a fantastic weight to combo (just gotta watch out for CC Shine) and you can Uthrow chain him. It's all about who gets in on who first, which is where Fox has a big advantage.
