Which is better during Umrah: reciting the Qur’an, glorifying Allah (Tasbih), and seeking forgiveness (Istighfar), or reviewing what has been memorized from it? And is their reward the same?

It is recommended to combine reviewing what has been memorized, reading from the Mushaf (physical copy of the Quran), and performing some dhikr (remembrance of Allah). If it is possible to combine increasing memorization with completing a full recitation of the Quran from the Mushaf, that is preferable. If it is not possible, then memorization takes precedence. If the review is for solidifying what has been memorized, then it takes precedence over reading something you do not currently intend to memorize. If it is not for solidification, then it is better to complete the recitation of the Quran in the Haram and read from the Mushaf to increase the reward for looking at it.
