Flamingo Fab Deluxe vs Harrah's Mardi Gras Tower/Carnaval Tower

Plans are underway for a solo trip to Vegas the weekend of the "Big Game" next year. With Total Rewards, I can get one of the following (price is for 4 nights, Sat thru Wed, with resort fees included):

Flamingo Fab Deluxe King - $299
Harrah's Mardi Gras Tower Room 2Q - $307
Harrah's Carnaval Tower Room 2Q - $309

I have never stayed at either property, so I was just looking for opinions about which place to choose (and if it comes down to Harrahs, which tower to select). I have watched some youtube videos on all three rooms, and they all seem fine to me. But just wanted to get some more feedback.

I was also going to inquire about a upgrade with a $20 sandwich, but being its Big Game weekend, I highly doubt there will be any upgrades available.

Thanks!

 

I just stayed at the Flamingo a week ago in a Fab Queen room. It was fine, plenty of room. Was on the 11th floor overlooking the Linq Promenade. Noise wasn't too bad, some loud music in the early evening sporadically but other than that okay. It might have been better in a higher floor.
I do remember hearing that rooms at Harrah's facing the carnival court are quite loud due to the bar and music from the bar in the evenings.
