Better than most isekai. Growth is seen from the MC as he grows fond of becoming an instructor via passing down his knowledge of the sword from his past life. This manga doesn't shy away from body dismemberment in the sword fights. 10 chapters in and we've already some heads removed, arms cut off, and people sliced in half. Hopefully, this doesn't turn into trash and has more balanced fights for our MC, though I'm betting this might have more of a OPM flair where everything is a struggle or a hard fought victory until the MC comes along to clean up.
