@Ursula
I think yours and
@urbanwild plants are different in terms of both leaf form and number of white spots (bumps ) on each leaf. Your plant looks like gasteraloe cv 'Apollo' pic below . Aloe Arista seems to figure on the genetics of both plants . It's such a common and hardy aloe and they hybridize so freely that there must be hundreds of crosses around . I think urbanwilds plant looks like Arista or a close hybrid like yours , crossed with a thinner and less spotty aloe 😀 flowers may give more indications but certainty in the world of aloes in cultivation is always a bit of a guessing game unless the plant is very typical of a species or named cv
