I'd go so far as to say the Expanse beats Battlestar Galactica. It's a classic for sure but too bogged down by the single self contained episode format that made it less enjoyable for me to watch.
Whoa, shots fired (joke). Seriously, I think when such a show reaches certain level of quality one does not need to pronounce one better than the other. They are so good they are worth your while. Of course, if we focus on specific aspects, you may be right. BSG was dark and very serious, paranoid/survival kind of stuff. Expanse is much easier to watch, you know nothing too bad is going to happen to main characters.
