Best option to format external hd for Mac and PC

Hi,

I have a new 2TB WD My Passport Ultra and I want to be able to read and write from Mac and PC. My main objective is to be able to access and edit videos and pics on both systems, thought I mostly use Mac.

What is my best option? Should I format in exFAT or in Mac OS Extended (Journaled)? Should I choose the later and install MacDrive 7 on the PC I may use? From my searches, Mac OS Extended is recommended for Adobe Lightroom users: why is that so?

I may have files bigger than 4GB (which excludes FAT32) and I am mostly using Mac but when I travel, I may use a PC and not necessarily with an internet connection, which excludes the Cloud option (except for backup). I will format the external hard drive on my Mac (Disk Utility).

Thank you!
