While the plots are relatively different, I felt like the Tales Of Zestiria and Sword Art Online had a similar atmosphere to them. Not only that, but the main characters in some way could be paralleled, without giving anything away (their identities, dialogue, it was all there). One is set in an RPG game and the other is a promotion for one, so I do believe if you have seen one or the other this would be up your alley.

Minus actual concept (Akagi revolving around gaming and YBJ around medical surgeries), both series give similar feelings...they did to me. I think anyone who has ever seen Akagi will immediately identify him with Jack, or vise versa. And the atmosphere in the two series is practically identical.

Both series contain a headstrong protagonist and an arch rival, who in one way or another ruined their pasts, so now protagonists seek revenge and are trying to find a way to stop them. The atmosphere in both mangas is similar when it comes to battles and will to fight as well as mythological themes.
