Is buying CS skins worth it?

I once bought a knife. While it felt nice to have, the realization of having a basically useless item that costs actual money which gives no benefit besides bragging rights (which nowadays is also not really the case since it's not rare to encounter people with knives in CSGO) however came pretty quickly and I sold it. Honestly speaking: If you really want some customization go with something very cheap that you want to stick with, but not having any skins does not ruin the experience a single bit in itself.
