Birthright offers a more traditional Fire Emblem experience. It tells a story of a rising hero defending their kingdom with the power of holy dragons, much like many other Fire Emblem games. It's a player friendly path that offers more opportunities for your characters to grow both in levels and in bonds with each other. This path rewards dedication and straight forward tactics, and is overall easier than Conquest.
Conquest offers a unique spin on the Fire Emblem narrative. It focuses on a truth seeker's attempts to quell the war from within, subverting a corrupt kingdom with the power of fell dragons. It's a path geared towards veterans of the series as it limits your resources and opportunities for growth. This path rewards careful budgeting and complex tactics, and is overall more challenging than Birthright.
Either way, both Birthright and Conquest should be completed before Revelations is played.
I wouldn't recommend one over the other. It should be your own choice.
