Bulk Up Talonflame is still good, but I run Flare Blitz / Brave Bird / Roost / Bulk Up. It's certainly not as immediately threatening as what the Swords Dance set is, but what it gives up in immediate power it makes up for with its longevity. Bulk Up makes it easier for Talonflame to keep setting up against some physical attackers. For example, Swords Dance Aegislash that tries to spam King's Shield against Talonflame won't enjoy being set up on. Swords Dance Talonflame is definitely going to be more consistent as a strong sweeper, but there's some merit to Bulk Up for sure.
