Vulkan is a quagmire of very low-level concepts, the danger of getting stuck in them and give up without learning anything is just too high.
At the same time making something with OpenGL that is more interesting than a simple rotating cube is not that difficult and you will get a lot of mid-level understanding - how rendering pipeline implemented and organized, what kind of task it is.
"Porting" this knowledge to Vk is straightforward.
