Which is better, air suspension or KDSS?

KDSS and air suspension are two completely different systems, each with its own advantages. Here is the relevant information: 1. KDSS chassis is an electronically controlled power-adjustable suspension system that improves off-road driving capability, stability, comfort, and handling. KDSS connects the front and rear hydraulic linkage rods to a closed system via a bidirectional hydraulic tube, replacing the small vertical linkage rods on the upper side of the front and rear anti-roll bars, as well as the accumulator in the middle of the two lines. 2. Air suspension can enhance vehicle stability and safety. Lowering the chassis on regular roads makes the vehicle more stable, while raising the chassis on bumpy roads helps avoid damage to the undercarriage, improving safety.
As someone who frequently drives off-road vehicles, I always find the height-adjustable suspension system more practical. On rugged mountain roads or muddy terrain, it can manually or automatically raise the vehicle's body, allowing the car to easily climb over rocks and water, preventing undercarriage scrapes. This is especially suitable for wilderness exploration or off-road enthusiasts. In comparison, KDSS mainly stabilizes the body during turns, reducing roll, which is beneficial for daily handling but less directly useful in extreme off-road conditions. Both have their pros and cons—height-adjustable suspension focuses more on traversability, while KDSS, a Toyota technology, emphasizes comfort and dynamic balance. If you often engage in outdoor adventures, height-adjustable suspension is the top choice; if you mostly drive in the city, KDSS is more hassle-free. You should also consider the vehicle model—hardcore off-roaders equipped with height-adjustable suspension are more formidable.
For my daily commute, KDSS is more suitable for me. It automatically adjusts the suspension during turns or lane changes, reducing body roll and providing a stable feel. Especially in heavy traffic or sharp turns at highway entrances, it makes driving smoother and prevents motion sickness. While the height-adjustable suspension is flexible and adapts to different road conditions, I hardly ever use it—city roads are flat, and raising the body height only increases fuel consumption and noise. KDSS is Toyota's patented system and is relatively simple to maintain, without much complexity. Unless you frequently drive off-road or in rural areas, I think KDSS wins in terms of daily convenience and comfort. The difference between the two is subtle, making them suitable for different scenarios.
