Depends on what type of worktop you are talking about. If your referring to a tool workshop, then neither, they are to expensive and will just get chipped and beat up.
If this is not the case then go with quartz, as it is the most durable, and the most expensive there is. You will see this when you go to buy it that quartz is the most
expensive.
Both Materials are technically very good. The quality of the product (the slab) is very good, but they are made with 2 completely different manufacturing process. Silestone is a Factory based in Spain, that uses a Breton System; Granite Transformations manufactures with a Vibration System in their plant in Sebring Florida. Silestone manufactures primaraly 3/4" or 1 1/4" slabs (2 or 3 cm), Granite Transformations 1/4" slabs (6.6 mm). Granite Transformations system is an overlay over an existing or new substrate, the only one of his kind in the world, while Silestone is a regular slab. Granite Transformations production uses high concentration of Recycled Glass, Recycled Porcelain, Granite and Quartz, while Silestone is mainly Quartz. Granite Transformations colors are different than Silestone, and when you get to color selection it is up to you to decide. Granite Transformations layover process allows the remodeling of a surface is a very short time and with minimum dust, Silestone installation is a regular installation.
Silestone claims their quartz is anti microbial, but when I tested it, it failed. Read their warranty info on this, they don't guarantee it will work. Pick a product that can be washed down with bleach water if you are concerned. Some granite will take this abuse, some will not. Most quartz materials won't cover bleach or cleaning product damage. Most solid surface (like Corian) will take the bleach just fine. There have been studies on copper countertops that showed antibacterial results. Two other studies that covered stainless steel, quartz, and granite were unpublished, written for pay from two industry trade organizations.
The answer is in the question. Natural granite and engineered granite are like steak and beefburger. However, engineered granite is probably more practical and cheaper in the long run. See link.

It depends on the granite or quartz you choose but generally granite is slightly cheaper.
Quartz is silicon dioxide (SiO2). Granite is a rock containing many minerals and chemical entities; but granite contain also an important percentage of quartz.
Diorite contains little alkali or quartz, while granite has more alkali and quartz. In between you have monzodiorite, quartz diorite, quartz monzodierite, quartz monzonite, and granodiorite.
Quartz will probably be found in most igneous and metamorphic rocks. Granite is a classic example of a rock with quartz in it. Search for images of "granite." Quartz sandstone is another rock practically made entirely up of quartz.
