Getting back into WWE!

So haven't been a big fan since the mid to late 2000s! But recently been watching clips and highlights and it's drawn me back in and would love to get invested again.

What's the best way to get started to get a feel for the current climate? Should I start from Royal Rumble 24 and work from there till now? What are the some of the major storylines I should catch up on through YouTube?

Also with smackdown vs raw, what's everyone mainly watching nowadays? Are they equally as good?
