HOTD is undoubtedly better. RoP needs to work in many things to get better. Specially the fuckin writing!
I've finished both.
I rate HOTD 9/10, better then GOT.
LOTR is 1/10 scenario, 8/10 visuals. Unironically black elf was the only guy whos acting wasnt cringe to watch.
Onions?
I’ve finished LOTR and thought it was decent, not especially good, not especially bad. Slow story, but I just want to mention again that there will be five seasons, so it’s kind of understandable. I rate it 6/10.
HOTD I didn’t finish, not because I found it bad, but I just lost interest eventually. I liked Daemon Targaryen and would have wished for him to be more badass and prominent in the show, I didn’t like the focus on the princess and queen. I don’t know how many episodes I watched (7 or 8 maybe?) and based on that I rate it 8/10.
