Wow, I hope the OP has made a decision by now. We're 10-ish years in!
I don't know what the draw to low profile reels is for saltwater. Just taste I guess. I just know round reels. I have some old Millionaire CV-Zs that are still going smooth and strong after 20-ish years. I picked up a new Calcutta 400B a while ago and still prefer my old CV-Z 300. However, it's hard to beat Calcuttas. Ryoga or Conquest? Only winner there is you. My wish list is a combination of Daiwa and Shimano. Just a bunch of Coke vs Pepsi, Camaro vs Mustang (CHARGER!

), McD's vs BK nonsense to me. You'll be happy with either.
I just don't know about this low profile in saltwater stuff. Guess I gotta try it.
