SAT books by Private tutors??

Are private SAT tutor books better than the big 2(princeton, barron and other big brands)
??
I have already taken Princeton SAT classes. What books should I go for
Famous booka from big companies or these highly rated books from private authors like-:
Maths - PWN, Chungs
English - Ultimate guide for sat, critical reader

Btw my current score is 1200.

Anyone can call himself a private tutor. Be careful to consider real content, not ttitles

Btw Im going for Princeton classes if that makes any difference.

I mean like the highly rated ones like the names I mentioned and College Board’s Panda. What do you think? how do they differ from the normal guides from Princeton etc?? I will be preparing over the summer break and give SAT a final time in September or November.
