hmmm... i will not prefer either... because shaving makes your hair little bit coarse and Nair may cause burning sensation. Go for laser or waxing, laser can be little bit expensive but it is worth as you won't have to bother for hair for next few months.. waxing is also good but can be painful, i remember my first time literally a cry came out of my mouth but its benifit is long term effect and also the hair which will grow will be smoother and can easily be waxed out.
