If you use grammar checker as a grammar checker, it wont make you loose your voice. It will make you use correct grammar.
> you can choose to use all the tools and make something gramatically and stylistically as close to perfect, but who would want to read something as dry
If it is dry, then it is not stylistically perfect. Per definition, dry writing is just an imperfect writing. Stylistically perfect writing does not have to be dry and usually is not dry.
What happens here is that people use "stylistically perfect" when they mean "followed a bad stylistic advice".
