If you care about ranks, sure.
I personally hate the FE7 style ranking system though, feels way too arbitrary and counter-productive (when you think about what makes for good tactics, deliberately deploying weaker characters and never using any of your good stuff does not come to mind, it's why I only like the EXP rank in FE4 because deployment isn't limited), plus it wasn't even set up properly in the game (Hector mode exclusive chapters don't get accounted for at all so their existence automatically lowers your tactics rank while making EXP and arguably Funds easier for no reason).
