First time viewer, need help with subtitles

Hi guys,

So I am planning to watch the series. Finally I have the time to do it. But I just found out that there are two different subs. CA and HiDIVE. I don't know which ones to choose. I searched and some say that CA is better. Others are saying HiDIVE is better. Others are saying HiDIVE is better for first two movies and S01. Some says that CA has more contrieved language while HiDIVE is more natural. I am confused.

Also there are no name tags in HiDIVE which makes it difficult for the first time viewer since they are so many characters. I was wondering if anyone can shed more light on which ones I should choose as a first time viewer.

Also how do I know which subtitle is which?

Thanks a lot.
