Which is suitable for traveling, Bali or Malaysia? Or is that island suitable for sightseeing?

Both Bali and Malaysia are suitable for travel and holiday.

Sabah is located in the east of Malaysia. Scenery includes: Kapalai Waterhouse (built on coral reef), Spatan (one of the top ten dive sites in the world), delicious food (white coffee, Lasha, Hainan chicken rice, bak Kut teh, coconut milk rice, seafood, ice cream), shopping (Sunday market, shopping center), beautiful island, and Crown Suspension Bridge (the bridge is built in the jungle more than ten meters above the ground).

Malacca, mainly China, Indian and Malaysian, is located in the west of Malaysia. Scenery includes: Dutch Red House, Zheng He Memorial Hall, church, display of batteries, planes and trains, ancient warships, graffiti, delicious food (Hainan chicken rice, ice cream), uncle's handwritten letter shop, Malacca scenic spot where you can take a cable car tour in human tricycles, and Ferris wheel.

Kuala Lumpur, Malaysia. It's just a big city, nothing special. The scenery includes the old railway station, the Twin Towers, the National Mosque, the Indian Temple and Independence Square (there are other attractions nearby).

To sum up, Malaysia's itinerary is more urban than Bali's. The trees in Malaysia are much taller than those in Bali. I like Sabah. I basically take a taxi, which is not expensive and the service is good. It is also within 20 minutes to walk from the hotel to the food street.

Bali, it takes 2 hours and 30 minutes to fly from Kuala Lumpur, Malaysia to Bali. Attractions include: Recommended Sea Temple (with beautiful natural scenery), Ubud Town (the cultural and artistic center of Bali, temples, small shops and restaurants can be seen everywhere, renting a motorcycle for half a day is 25 RMB, and it is very convenient and cheap to spend all day in 35 yuan. Attractions include Lotus Restaurant, Ubud Palace, Three Monkeys Restaurant), Kimbaland Beach Seafood Barbecue (expensive), Ayana Hotel (there are two churches, and the top ten rolling stones bars in the world watch the sunset), volcano, Kuta Town Bar and food, surfing, two lovers' spots and Blue Point Hotel (Blue Point Hotel restaurant is not expensive either, there is a white church in the hotel, and the private restaurant below him is cheap and beautiful).

To sum up, the trip to Bali is less urbanization and more leisure, mainly hotel tours, staying in hotels with good environment, and spending most of the time in hotels. If you travel in depth, you can start from Ubud town and see the volcano in the middle.
