The thickness is usually relative to the 'years' of warranty on the cover.. the thicker the cover, the more layers, or thicker layer of protective/insulative coating on the core of the solar blanket. In my experience it is worth buying the extra thick cover. they are much more durable , which is good because the corrosive nature of the water over the years.
Yes, a thicker pool solar cover can help heat the pool faster because it provides better insulation and helps to retain more heat in the water. Thicker covers also tend to be more durable and last longer than thinner covers.
First, the small variation in thickness between makes and models of solar pool covers will not significantly change the amount of heat absorbed by the water. That being said, a thicker pool cover may be more tear or damage resistant than a thinner cover and thereby, last longer. But it may also be more expensive and heavier, especially when wet as you pull it out of the pool. Hope this helps ...
It's not possible to add optimizer plus to a pool with the solar cover on. You will need to remove the solar cover from part or all of the pool in order to put optimizer or other pool treatment products into your swimming pool water.
Useless
They are the same thing basically. Pool Cover, Solar Cover, solar Blanket are all used interchangeably. It's basically some material, usually a plastic bubble mesh or vinyl covering that goes over the pool. The exception to this is Winter Cover which generally is heavier and designed to protect your pool during long winter months.

when you are in the pool
A solar pool cover can help increase the temperature of a pool by around 5-10 degrees Fahrenheit depending on factors like sunlight exposure and pool size. The amount of heat gained will vary but generally, solar pool covers are effective at harnessing solar energy to warm up the pool water.

It is depends on the type, brand and size. It cost about $219 for the 10m x 6m solar swimming pool blanket cover and $512 for the solar pool cover 500 micron series.
It would be stronger but possibly harder to handle depending upon size. K
