Depends in the hobby shop, some "modelling" glues are simply overpriced.... there are lots of proprietary brands around the world that do the same thing.

My personal preference is Loctite, there are several types and one suggestion I have is not to buy big bottles - the small amounts used for models tends to leave a large bottle open a long time and the consistency changes as the solvent evaporates. This can however sometimes be an advantage - my older glue is thicker and doesn't act instantly.

Some Super glues contain 'filler' to give them some shock resistance, this can be at the expense of overall strength but again can be useful properties.

Thinner - acetone, also cleanup and debonder - careful it won't eat your subject!

Finally, and this is from a personal experience, I would recommend wearing safety glasses - I almost got some in my eye when two parts snapped together as I was assembling a tight joint and the glue squirted out into the area next to my eye and nose. Very lucky to miss a trip to A&E....
