The difference between the OmniPoint and the QX2 switches from SteelSeries lies inSeveral key aspects:

## Actuation Point and Customisability
- OmniPoint Switches: These switches are extremely customisable, with an adjustable actuation point from 0.2mm to 3.8mm. This allows for customisation for each user, which is especially useful for gamers who prefer specific settings for their games.
- QX2 Switches: These switches are more traditional mechanical switches with fixed trigger points. They are available in linear, tactile and clicky versions, but are not as customisable as the OmniPoint switches. The trigger point is approximately 2 mm.

## Response time and speed
- OmniPoint switches: These switches have a response time of around 0.54 ms and are very fast and reliable thanks to their magnetic sensors. They also offer the option of configuring two different actions for the same keystroke.
- QX2 switches: These switches have a response time of around 6 ms, which is significantly slower than the OmniPoint switches. However, they are still suitable for gaming, but offer less customisation options and speed.

## Durability
- OmniPoint Switches: These switches are designed for 100 million clicks and are characterised by their durability and resistance to wear and tear.
- QX2 Switches: These switches are designed for 50 million clicks, which is less durable than the OmniPoint switches.

## For gaming
- If you're looking for the best switches for gaming, the OmniPoint switches are more worthwhile. They offer higher speed, better customisability and longer durability, making them ideal for competitive gamers.
- However, the QX2 switches are still a good choice if you prefer more traditional mechanical switches and are less reliant on extreme customisability and top speed.
