W2 vs 1099/Sole Proprietor

I am in sales and have the option of being a w2 employee or a 1099/sole proprietor. From a deduction perspective I already deduct my home office and other non-reimbursed business expenses (vehicle, etc.) as a W2. My question is: Will I benefit from becoming a 1099/sole proprietor from a tax perspective? Does this open me to more opportunities for deductions? Does the Trump tax plan help me?
