Starts with exactly the same type as a japanese guy getting reincarnated in a land of magic and fantasy. More like a game setting.
Both of the main protagonist are related to games in their previous lives and died at their 30's (around). But they turn young when they get reincarnated into an unknown world. Magic becomes their first use into the new land too.
Difference between them is in Mushoku Tensei the story becomes gradually more deep and dark but in Death March the story stays enjoyable and light.
If you like one of them be sure to give the other one a try.
