It wouldn't hurt to read some of the MSDN documentation; they state:

The Dictionary< (Of < (TKey, TValue> )> ) generic class provides a mapping from a set of keys to a set of values. Each addition to the dictionary consists of a value and its associated key. Retrieving a value by using its key is very fast, close to O(1), because the Dictionary< (Of < (TKey, TValue> )> ) class is implemented as a hash table.

The SortedList< (Of < (TKey, TValue> )> ) generic class is a binary search tree with O(log n) retrieval, where n is the number of elements in the dictionary. In this, it is similar to the SortedDictionary< (Of < (TKey, TValue> )> ) generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal: ...

hence performance is the key; you choose based on (1) the need for having things sorted, and (2) the balance between insertions and lookups.
