I love both games, i consider Fire Emblem Path of Radiance as good or even better. it is more entertaining because the gameplay is more simple, it is not very much about classes and leveling but more about using units/maps to your favor, more like a chess game. Path of Radiance wasn't a big seller and the GameCube as a system wasn't very successful so a lot of people didn't play the game, but its up there with the very best.
The story is very smartly written. Fire Emblem as a series usually feels more idealistic than Matsuno's stories but Path of Radiance did a fantastic job to show the two sides of an argument using characters with different and clashing view points like Titania and Soren from the Greil mercenaries. it is a story about politics, nations, war, racism, and courage. like FFT, its full of great and touching moments. it is still a little more idealistic than FFT.
Actually, Hironobu Sakagutchi was always a fan for the Fire Emblem series and it was the main reason why Square wanted to make a FFT game.
Another fantastic game that you may like from the series is Fire Emblem Echoes, it is more similar in its gameplay to FFT than FE games that came before. it also did go back to more grounded storytelling after Awakening and Fates.
It looks like Three Houses will be fantastic.
