Which one is better: tahajjud or qiyam al-layl?

Asalaam alaikum Which one better between tahajjud and Qiyam layl

Alaikumassalam wa rahmatullah,

Tahajjud is normally considered more virtuous due to it being more difficult, since a person has to interrupt their sleep to do it. But I believe God rewards us based on our efforts, so it depends on each person’s situation. So regardless of whether you perform tahajjud or qiyam, your reward depends on what you do with the time and abilities that God has given you.
