I'm not sure why you can only like one or the other. I'm really enjoying Divinity: Original Sin. It's a great game, but I also like the Dragon Age games. DA:O was very good, DA2 was kinda meh, but had an ok story. I'm looking forward to Inquisition, hoping it's learned for the mistakes of it's predecessors. I'm also really looking forward to Pillars of Eternity, Torment, and even just threw 20 bucks at the Kickstarter for After Reset.
Different games fill different spots for me. Bioware games are the giant summer popcorn movies. They have to have mass market appeal to make enough money to pay for their massive production cost. That doesn't inherently make them bad. Besides, other then the huge stumble at the end of ME3, I feel they usually tell a reasonably good story. Divnity is the lower budget Indie Sci Fi movie that hopefully becomes a huge hit, like Star Wars was once upon a time (for those of us who remember when Episode IV first came out.)
