Is using Pressure based Coupled solver recommended Natural Convection problem?

Hello why is the use of Coupled solver suggested for Natural Convection flow? For a Natural Convection flow isn't the P-V coupling always weak and it is actually the Energy-Momentum coupling that need to be taken care? If this is the case then using Fluent Coupled Solver shouldn't be helpful as only Continuity and momentum equation are solved in coupled manner and Energy is solved separately in segregated way.

Does any one have any info on this ?
