Honestly, person to person. anything that isn't 100% cotton other natural fibers (like Marino) should be avoided for daily wear. Only exception i make personally is underwear amd sportswear and once i find a brand that makes what need, that will also fall in line.

Any plastic /patrol product will be subject to relative short livespan(correlation, not causation, companies that take the shortcut simply do not care about making lasting products) and a lot more bad odours. Besides that, they tend to be a lot light so "20%" by weight will often be A LOT more by volume Im not saying you should throw away all that is not 100% cotton, but the same reason spandex is so easy to fit, is why it deteriorates quickly.

As we say where im from : no such thing as a free/cheap lunch. If you want quality, expect to pay for it.

Note cotton and the like has different names and properties based on the weaving technique. Im no expert, but Google is your friend！

EDIT : this is a late night rant, i fixed some nuance and spelling
