No, Queen wasn't portrayed to be comparable to King.
They are both introduced as decisively superior to Jack who's afraid to talk back to either of them, while they are interacting with eachother from an equal standing.
They are both said by Zoro to be difficult opponents to overcome in order to reach the roof, not making either of the paths guarded by them stand out as easier for him.
They are both talked about in the same breath by Marco as difficult opponent to hold out against.
Queen has an insanely high bounty for a YC with his 1,320 billion. We just recently got confirmation that Marco's bounty is bellow 1,5 bil, making it likely comparable to Queen's or potentialy lower.
That's possible seeing how we have another YC1 with "only' 1,057 bil on his head.
So with Queen having that high of a bounty, with 320 million higher than Jacks, and the difference in portrayal where a billion beri man get's bullied by him, it's also very likely that King and Queen's bounties are a lot closer to each other.
King and Queen are also highlited as Kaido's men who have been at his side since the moment he came to Wano. We've seen only the two of them among his current officers acting as Kaido's muscle in the flashback and pushing back the Scabbards while Kaido faced off against Oden.
This detail is significant, because we see that Kaido's crew functions based on a meritocracy system. We've seen that Beast Pirates get a chance to challenge the All Stars for their positions, so this means that King and Queen are the only one's who have managed to maintain their top two spots for over two decades, defeating any challengers along the way.
Oda also went as far as to give Queen the special treatment he usually gives to the YC1's among commanders, by making it so that there's something special about him beside his DF power. The way King does not only have an ancient DF but is also part of an special race, Queen does not only have an ancient DF but also a modified body with unique enhancements that further boost his durabiliy, physical stats, and arsenal of weaponry, on top of the Plagues that he can unleash upon his opponents.
They have absolutely been portrayed as comparable, and hyped up to stand that much above any other Beast Pirate, even the fellow current All Star, the 1 bil man who acts like a scared child would around their bully when talking with the likes of King or Queen.
Chopper's strongest attack with Marco's help barely made him excited, then he started petting the poor Chopper
