Synthetic vs natural salt

What’s the benefits of natural vs synthetic sea salt

I am currently (5 months) been using a synthetic sea salt by aqua forest and have been having good results in a lps dominated reef tank. However I was contemplating going to a natural sea salt by Red Sea.

Has anyone had any experience with either of these and are there benefits to either?

Any issues changing between natural and synthetic?

There is no "natural" salt, unless you just collect seawater and use it without drying. if you dry it, some things precipitate and cannot redissolve to reconstitute normal seawater. Calcium carbonate is one, so calcium and alkalinity will not return to normal levels.

Red Sea gets some of the components from purified dried seawater, and adds in others. It's misleading to say this is natural seawater. Even normal table salt and other chemicals are made by stepwise drying of seawater in many parts of the world.

Both salts are fine, as are most brands.
