B&W, or Colour?

Out & about for work today, I had the chance to snap a couple of photos of a large storm off Manly Beach. Whether it was the same one that rolled over the top of WaitingManor at 3am, shattering the night-time silence with an almighty CRASH of thunder, followed shortly after by ANOTHER ONE!!! is unknown...

I can't decide if I like the colour photo, or the black & white one. Here are both, then...
