Different authors bring different flavors. I like Rushdie, for his language skills; Ishiguro, for his fluid stories; Amitav Ghosh, for his research on the subject; Ayn Rand, for her powerful and convincing philosophy; Orwell, for his timeless political satires -'Animal Farm'and '984' There are others too, the latest one to enter my favorite club is David Mitchell, for his 'Cloud Atlas'
