In both series the MC is taken into another world, but in Mushoku Tensei the character is reincarnated while in Tate No Yuusha the character is simply transported still both series have great Main Characters that you will love and I would recommend both series to anyone since they are great.
In both novels the MC is transported/reincarnated to another world. Both the worlds are like games and have magic and fighting.
If you like funny, game-like worlds then I'd definitely recommend you read both.
