I've never actually read a comic
I find the format very hard to follow. However I know a LOT of DC and Marvel lore from "reading around" the comics on various Wiki sites. Overall I prefer DC lore to Marvel lore, I find Marvel lore a bit over-stuffed when everyone exists in the same world. I actually think Marvel cinema has benefited hugely from MCU and X-men being confined to their own separate universes and if they do merge X-men into the MCU both franchises will suffer.
