Its Malaysia hands down when you want nature view. Singapore is a very good place to visit when you want to be amazed how a small country ( 2 hours to cross country) could transform into a commercial and industrial success . I've been to Singapore five times for business , and find the place efficient , safe and peaceful. Everything you could do on schedule , they have great transportation system , progressive commercial establishment , good people and average environment but a little staid (plain ) because people could only choose discipline and decency, or they would be dealt with accordingly . Malaysia is vibrant because in a place where people have a choice to be descent and discipline most choose to be descent and disciplined .The people are a good mix of Muslim , Christian , Buddhist and other religion but they coexists peacefully and brotherly .. I took the cross country drive from Kota Kinabalu to Brunei passing Sarawak , Limbang and all the provinces of Sabah and stayed in Mt Kinabalu of Kota Kinabalu for two nights . Talk about nature drive , the snow capped mountain , the untouched my human hands Mt. Kinabalu and the various flora and fauna abound as you drive up to Limbang are amazing . The mountain ranges and the Palm tree lined highway are just surprising and everytime you look at all sides , you know Malaysia is blessed so many times over . Not to mention the vibrant Kuala Lumpur where everything happens , great bargains on clothes , electronics of all brands and kind and if you want signature(you have so many in Dubai ) KLCC, Petronas Tower is a marvel . Visit Malaysia.
