I go with team burm. I have had both, currently have a burm. It absolutely comes down to personal preference. Both are massive snakes with incredible feeding responses, warranting a high level of care, consideration and experience once they get big. Personally I like how burms interact and move much better than retics. Once adults, a lot of burms I have seen become these big 'dopy' and almost goofy snakes that kind of 'lumber' around. Retics move much quicker and are seemingly decisive and cunning in their actions. Looking into a retics eyes you can almost see them logically working through a situation

That being said I am likely picking up a hatchling albino retic in the upcoming weeks.
