Dropper post: cable, hydraulic or AXS
There are three ways to actuate a dropper and none is best in absolute terms: 1) cable (mechanical) — the most common, reliable, cheap and easy to service, with some cable friction; 2) hydraulic — fluid actuation, smooth and sealed feel (like the old Reverb), but harder to bleed and service; 3) wireless AXS — no cable, clean cockpit, but expensive and with a battery to charge. Choose by budget, maintenance and cable cleanliness.
The actuation doesn't change what the post is for, it changes the price, the maintenance and how the cabling ends up. That's why it's worth choosing carefully.
The three types, one by one
Cable (mechanical). The most widespread and our default recommendation: reliable, cheap and easy to service. An inner cable pulls the valve from the lever. Its only weak point is some cable friction, more noticeable if the routing is dirty or very tightly bent.
Hydraulic. Instead of a cable it uses pressurised fluid, giving a smooth, sealed feel (the old Reverb is the classic example). In exchange, it's harder to bleed and service when it fails, and needs specific tools.
Wireless (AXS / electronic). No cable or housing: the lever sends the command by radio and leaves a spotless cockpit. The price is high and there's always a battery to charge. It's the premium option for looks and convenience, not for descending performance.
Key facts
What it fits with
Before choosing an actuation it helps to be clear on what a dropper post is and to check how your frame is set up for internal or external routing of the cable. That decides whether a cable dropper will give you trouble or run smooth.

Frequently asked questions
Which is best?
None in absolute terms. Cable: common, cheap, easy to service, with some friction. Hydraulic: smooth feel but harder to bleed. AXS: clean cockpit but expensive and with a battery.
Is cable worse?
No. It's the most common and the easiest to maintain and repair. It only loses some feel to cable friction.
Is AXS worth it?
If you value a cable-free cockpit and have the budget, yes. If you want simple and cheap, a cable dropper does the same job.
