Hi

As the title suggests, my question is pretty straight forward, yet I couldn't find an answer online.
I will be arriving to Phuket in April for 7 days and staying in Surin, doing my maths i came to the outcome that renting a car will be cheaper (4300 THB for 7 days) than using taxis for airport transfers + moving around the island (1500 for one airport transfer, surin>patong at least 500THB oneway).
Now, I read horror stories about car driving in Phuket but living in Europe I dont quite have the picture what it means in reality, the closest region-wise I experienced was driving a month ago in Langkawi (which was TBH very comfortable with no problems at all, i had 10x more stress when I was renting a car in Paris . So my question is thus, how would you compare driving a rental car in Phuket as to in Langkawi
Many Thanks
