The differences are usually slight to most people.

Such as 100% natural is slightly softer, slightly more breathable and slightly more natural!

I always use the comparison of a decent wine vs a fine wine.

To some the difference is noticeable, but to most palates they are very similar.

There is an argument 100% natural latex is more durable in the long term, but by the time you get to 80% and above you’re already in the serious high quality zone!

In a nutshell 100% natural is the best quality you can get and as soon as you introduce synthetic you start to water down and dilute that quality.
