Both taxis and private transfers are widely used from ICN. Here is how they actually compare.

When the taxi wins
During daytime hours, taxis are quick and readily available. The queue moves fast and you rarely wait more than 5 minutes. If you speak some Korean or are comfortable with translation apps, a regular taxi is the cheapest car option. International taxis (black sedans with English-speaking drivers) are a good middle ground.
For short distances or when you are alone with light luggage, a taxi is simple and efficient.
When the transfer wins
The language barrier is real in regular Korean taxis. While most drivers use translation apps and navigation systems, communicating a specific address or dealing with changes can be frustrating. A private transfer with an English-speaking driver removes this entirely.
At night the taxi surcharge plus tolls can push the total fare close to or above a pre-booked transfer price - and the surcharge peaks at 40% between 23:00 and 02:00, not the flat 20% most guides quote. The transfer price does not change regardless of time.
For families needing car seats or groups needing a larger vehicle, private transfers are the only practical option from the taxi stand.
The AREX alternative
Before choosing between taxi and transfer, consider that the AREX Express gets you to Seoul Station in 43 minutes, and the All-Stop train does it for KRW 4,750. If your hotel is near a subway station, this is faster and far cheaper than either car option. Save the transfer for when you actually need door-to-door service.
The bottom line
If you arrive during the day, speak some Korean or are adventurous, and have simple luggage, take a taxi or the AREX. If you arrive late, have kids, want English communication, or prefer certainty, a private transfer is the smarter investment.
