Tough call. I know you are going to get a LOT of different Q&A's on this question.
Questions:
1. In any price range?
2. For what?
3. Production or custom?(ok, custom doesn't have so much a lineup)
4. By sales volume?
5. By profit?
6. Insert question here
Very much, it depends on personal preference. Rather you prefer fixed, folding, or auto(yes, I know its a folding, but it is a different beast). Rather you prefer tactical or non.
The most versatile lineup(and most disputed) in the sub-$200 price range would seem to be either Spyderco or Benchmade. I guess overall, one of these may be considered "best."
However, looking in folders only, it would seem that the Microtech line owns a certain reputation for ravenously defensive fans. Although I don't own one yet, I plan on it soon. Very good lineup of knives.
Going well over $200.00(though still in production) there are the Chris Reeves Knives(although, not as large a lineup) and the Busse Knives, also more limited. From here, you could go higher into customs, but here would be either an endless "lineup" of knives, since they make whatever you contract with them, or a very limited "lineup" since they will only make(usually) one of what you want and it isn't readily available to everyone.
It would seem, the higher you go pricewise, the more focused the maker is on a smaller lineup. This ensures (IMHO) the ability to have higher QC(quality control) of the lineup.
So, IMO, to get the most versatile lineup of knives, I would look to Spyderco or Benchmade. They both have a fairly large selection of both fixed and folder. Both have highly touted knives. And, the very fact that such heated arguments surround the two, would reveal two good knife companies with good product. After all, who would defend crap?
Note: I have not included all knife companies in this, due to the fact that my synopsis does justice to the question at hand. If I left out your favorit lineup, it was not meant as a slight, just an omission to save space. I tried to make examples in various price points. Of course, there are more(many, many) more brands which are very worthwhile.
For example, REKAT. They are perhaps my favorite brand of knife at this moment, but I only include them in this note, because I feel they don't have the absolute greatest lineup. However, if looking for a working knife, I would highly suggest their lineup as a very strong and excellent product.
