Whichever one you select I think you will be pleased. The 3594.50 BA is a bit of a chameleon, a tool watch that is a bit dressier than the standard speedy. The broad arrow hands can be a bit harder to read and can obscure the chronograph hands depending on the time of day. Having said that, it is a fun watch to wear and one you'll likely never see on anyone else in the wild. The 3594.50, which has a very dark gray dial, hasn't been made in 17 years. The guy at the Omega Boutique commented that he had never seen one before he saw mine.
I own both watches and FWIW I wear the moonwatch more often, possibly because it is on a brown strap and the BA is on a black strap. I own a lot more brown shoes than black ones so I wear brown watch straps more often.
BTW, there is not a scratch on the hand. The photo below shows the Omega symbol in the crystal being reflected off of the hand.
