When somebody asks you for your Bitcoin address because they want to send you some, give them the bolded address.

Each of those represents the same Bitcoin key, but they are very clearly different.  You will always be able to use the legacy Bitcoin address format, aka the first one.  I can't imagine any wallet software not letting you see a legacy version address of any of your public keys.
