Depends what your needs are. Polyester dries faster, so for something such as a swim suit, it would be better than cotton, in that respect. The color in polyester also isn't as likely to bleed in wet conditions. So a multi colored item is less likely to get murky in the wash.
Probably the most important way that polyester is better than cotton is that it does not shrink in the drier, unlike cotton; however, cotton is generally softer than polyester.
where the cotton percentage is more than 50% in the yarn (cotton polyester) than it is termed as cotton polyester and where the polyester percentage is more than 50% in the yarn ( polyester cotton) it is termed as polyester cotton.
100% cotton is more durable than cotton and polyester blends because it less stretchy and therefore less likely to rip.

In a fabric comparison test, 100-percent polyester provided better UV protection than both cotton and a polyester blend. When there are UV warnings, it is best to avoid wearing cotton fabrics.

Cotton is more expensive than polyester, as it is grown, whereas polyester is man-made and easier to get.
Polyester cotton tends to be more water-resistant than denim due to its synthetic fibers, which can repel water better than the natural fibers found in denim. Denim is typically made from cotton, which absorbs moisture more easily, making it less water-resistant overall. While both fabrics can be treated for water resistance, polyester cotton generally offers better performance in wet conditions.
Everything is essentially biodegradable. Cotton with polyester blended in, or polyester alone will take longer to biodegrade than 100% cotton, for example.
Cotton blend could be mixed with polyester.
Yes. They reduce friction for longer spin times. They also often come in thinner strings. For a beginner, cotton is better, but if you are looking for a string to use for an unresponsive yoyo, polyester would be the best choice.
