The best technique for handling collision in hash tables largely depends on the specific requirements and constraints of your application. Here's a brief overview of each technique:

a. Linear Probing: In this method, when a collision occurs, the hash table checks the next available slot to store the value. This method is simple to implement but can lead to clustering, where a large number of consecutive slots become occupied.

b. Double Hashing: This method uses a secondary hash function to find another slot whenever there is a collision. This reduces clustering and can result in a more evenly distributed hash table.

c. Separate Chaining: In this method, each slot in the hash table holds a linked list of key-value pairs. When a collision occurs, the new key-value pair is added to the end of the list. This method can handle a high number of collisions but uses more memory.

d. Quadratic Probing: This method is similar to linear probing but instead of checking the next slot during a collision, it checks the slot that is a quadratic distance away. This can reduce clustering compared to linear probing but is more complex to implement.

In general, separate chaining is often preferred when the load factor is high (i.e., the hash table is relatively full), while linear or quadratic probing may be more suitable when the load factor is low. Double hashing can be a good compromise between these methods, offering good performance in a variety of situations. However, the "best" method really depends on the specific characteristics of your application.
