When I was a student, I did not like to go to Tsuen Wan...... you know, a student may want to buy something at Sha Tsui Rd.... At there, it was VERY VERY hot. But I guess your targeting court is a bit far from Sha Tsui Rd. Because there is a hill view at south-east......
If you need to go to Sha Tsui Rd for shopping or eating, please take a look at there first..
Other than that, I shall choose the south-west one....I think it would be windy......
If you do not mind to wake up early, you can choose the south-east.
