Will a better quality white stain resistant and wrinkle resistant ??? ?

be easier to maintain clean and easier to clean whenever the time comes to it.  I am a security guard. The shirts they provide to us leave a lot to be desired there are mass-produced and I know they're made out cheap material.  I am wondering if I go buy a better quality white dress shirt that stain resistant and wrinkle resistant will be easier to clean in the long run.  The shirts they provide us now I'm at my Wit's end how to get them clean. I put shout on them before handle let them sit for a good 20 minutes.  I use tide laundry detergent, bleach, OxiClean and the stains are that stubborn they still refuse to come out. I hate to spend $50 on a supposed stain resistant shirt and end up with the same results.   As you can see here their shirt is not very clean and this is after it's been washed and dried.
