ACT Prep books?

So I got the Barron’s ACT prep book along with AP language and composition. Are they good books to study from? I heard the content was good but the practice tests were mediocre .I will be taking the ACT for the first time this year and AP language and composition exam .i will be taking the SAT on May 5th of this year . I don’t know when I’ll take the ACT . Does the ACT have more trig on it than the SAT ? Which test (ACT or SAT) would you recommend for an algebra 2 student? I’m currently in algebra 2 . Thank you
