Fruit (including apples, bananas, and others).
The Case 1 "megaHub" will only really attract visitors and search engine traffic for people looking for "fruit", and maybe just a few for the fruit you've said are included, like "apples" and "bananas". Google or Yahoo, the most popular search engine, will conclude that you've created one really great resource on "fruit". However, in Case 2, Google or Yahoo will send people looking for those specific types of fruit ("apples", "bananas", "lemons", etc), and a little looking for the general term "fruit".
In fact, with each additional specific fruit Hub, you're more likely to have the search engines send you traffic for people looking for "fruit" -- all the more reason to continue, and create Hubs for blueberries, grapefruit, and persimmons. Google and Yahoo will send visitors looking for the general term ("fruit") AND all those looking for "apple", "orange", "lemon", etc.

The final piece in the traffic puzzle is to create a number of Hubs around a single topic. Think of this as a numbers game: the more Hubs you have out there on a certain topic, the more possible entry points there are for readers into your entire pool of Hubs. Simply put: the more you publish, the more readers you get!
Search engines like multiple, clustered articles on a certain topic, too. It's an example of the whole being greater than the sum of its parts: a multiplier effect. Let's take a look at an example.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
