Do not choose KTX or a long-distance bus from the vehicle name alone. Compare 출발지 (departure point), 도착지 (destination), 소요시간 (travel time), 요금 (fare), and 환승 (transfer). The right choice is the one that reaches the correct station or terminal at a useful time for your trip.
KTX is a high-speed train. 고속버스 is an express highway bus, while 시외버스 is an intercity bus. Their routes and booking systems are not identical, so search the exact departure and arrival points before comparing results.

Pronunciation

The Korean word 역 marks a rail station. 터미널 marks a bus terminal. A city may have more than one station or terminal, so "Seoul" or "Busan" alone is not enough information.

Ask yourself two questions:
1.
How long does it take to reach the departure station or terminal?
2.
How will you travel from the arrival station or terminal to your accommodation?
Useful Korean questions are:
Korean
Meaning
이 기차는 부산역에 도착해요?
Does this train arrive at Busan Station?
이 버스는 어느 터미널에 도착해요?
Which terminal does this bus arrive at?
여기서 시내까지 얼마나 걸려요?
How long does it take from here to downtown?
호텔까지 갈아타야 해요?
Do I need to transfer to get to the hotel?

Read the time correctly

Korean
Meaning
출발 시간
departure time
도착 시간
arrival time
소요시간
travel time / duration
첫차
first departure
막차
last departure
지연
delay
운행 중
operating / in service
운행 종료

소요시간 2시간 40분 means the scheduled ride takes two hours and 40 minutes. It does not include the trip from your hotel to the station or from the terminal to your final destination.
For a bus, road conditions can affect the actual arrival time. For a train, you still need to allow time to find the platform and board the correct service. Compare the complete travel chain, not only the number under 소요시간.

Direct, transfer, and stops

Korean
Meaning
직통
direct
환승
transfer
환승 1회
one transfer
갈아타다
to transfer / change vehicles
무정차
nonstop
경유
goes via / stops at
정차역
station where the train stops
On KORAIL's current reservation page, the detailed conditions include direct-route and transfer choices. Check whether a result requires 환승, especially when you are carrying luggage. The official English KORAIL reservation page lets you compare the specific stations, date, passenger count, and route conditions.
Ask staff:
갈아타야 해요?
Do I need to transfer?
어디에서 갈아타요?
Where do I transfer?
The answer 대전역에서 갈아타세요 means "Transfer at Daejeon Station."

Compare fares without assuming one is always cheaper

Korean
Meaning
요금
fare
운임
transportation fare
일반실
standard train class
특실
first-class train car
일반
standard bus class
우등
deluxe bus class
프리미엄
premium bus class
할인
discount
Compare the fare shown for the exact date, route, and seat class. 우등 and 프리미엄 are not the same product as a standard bus seat, just as 특실 is not the same as 일반실 on a train.
Useful questions include:
Korean
Meaning
일반 좌석 얼마예요?
How much is a standard seat?
이게 가장 저렴한 표예요?
Is this the cheapest ticket?
우등하고 일반이 어떻게 달라요?
How are deluxe and standard different?
할인되는 표가 있어요?
Is there a discounted ticket?
Avoid copying a fare from an old blog post. Prices, seat availability, and schedules can change, so confirm them on the booking result you are using.

Read availability and booking status

Korean
Meaning
잔여석
seats remaining
예매 가능
available to reserve
매진
sold out
좌석 선택
select a seat
현장 구매
purchase at the terminal
모바일 승차권
mobile ticket
예매 완료
reservation complete
예매 내역
reservation details
매진 means that result is sold out. It does not tell you whether another departure, seat class, station, terminal, or booking system has availability.
BusTago's official guide shows that its intercity-bus search uses the departure, destination, date, available schedule, and seat selection, and that some results may be marked 현장구매. Check the current route on the official BusTago reservation site. For express buses, also check the official KOBUS site, because a route may not appear in the system you searched first.

Questions at the station or terminal

Korean
Pronunciation
Meaning
부산 가는 표 있어요?
bu-san ga-neun pyo i-sseo-yo

모바일 승차권으로 타도 돼요?
mo-ba-il seung-cha-kkwon-eu-ro ta-do dwae-yo
Can I board with the mobile ticket?
승강장 can refer to a boarding platform or bay. Follow the number on your ticket and the departure board.

A comparison script

You: 경주 가려고 하는데 KTX하고 버스 중에 뭐가 편해요?
Staff: 숙소가 어디예요?
You: 황리단길 근처예요.
Staff: 기차역에서 버스를 한 번 더 타야 해요. 터미널 위치도 확인해 보세요.
You: 소요시간하고 도착 위치를 비교해 볼게요.
The staff member asks where your accommodation is, then tells you to check the extra connection from the train station and the bus-terminal location. The answer is not "KTX is always better" or "the bus is always cheaper." It depends on the exact route and endpoint.

A five-point decision check

Before paying, compare:
1.
출발지: Can you reach the station or terminal easily?
2.
도착지: Is the endpoint useful for your hotel or attraction?
3.
소요시간: Does it fit the whole travel day?
4.
환승: How many changes are required?
5.
요금·좌석등급: Are you comparing equivalent seat classes?
This keeps the article's answer stable even when a fare or timetable changes. Read the Korean labels, compare the live results, and choose the trip that works from door to door.
