Is... Is it always this aggressive on here?
Either way, my unpopular opinion is that Radiant Dawn is a really really bad Fire Emblem game and is by far my least favorite.
Again, 100% opinion and preference though.
I'm an incredibly character driven person, and I just don't like the way characters are presented in RD or PoR really. I don't like how outmatched a lot of characters are either, I always felt like a character was either always worse than someone else, or were incredibly overpowered.
My favorite game is Thracia 776, which I also think is just preference, but I do think it's a legitimately good game.
Though characters don't have much dialogue, I think what is given is really interesting and has a lot of potential. I also enjoy how you can really make any character viable, and while there are certain OP ones, I think it's overall really cool to not really have necessarily "bad" characters that require insane levels of babying.
Because of this I also find Thracia characters to fill up most of my favorites. I really like their fairly realistic and grounded designs, and I think that the darker, non-bright colors help it feel much more interesting and BA. I love the potential of characters like Hicks, Fred, Kain, Robert, Carrion, and Glade. There are so many other interesting characters too, but to address all of the ones I think look cool AND the reasons why would take forever.
Overall I just really love Thracia, how you can forge your own playthrough uniquely every time, how the character designs are just grounded and realistic, and how the story is great and has amazing potential if expanded upon. I especially love the first one, there are so many ways to solve problems and it's really fantastic, my run is completely different from your run. No one can convince me that Kain doesn't canonically have Wrath, or how Fred doesn't canonically have Sol. It's just so cool.
