I didnt hate all of these, but they either didnt' work or weren't what I wanted:
BJU: liked how easy it was, son was bored to death with the videos, and it costs a fortune
Sonlight: EPIC fail for us....hated it....didnt like many of the books and the choppiness of the daily plans switching between books
Shurley Grammar: dry, boring, and really way too much info for the early levels
Math Mammoth: tried it for 3rd...some of it was good....some of it my engineer husband coudlnt even figure out how the text was trying to explain a simple concept
Singapore Math: it looked like Greek to me
Teach your Child in 100 Lessons & Ordinary Parents Guide to Reading: caused tears daily in my daughter
ACE: it works, it covers things, its dry and boring and too watered down
Sequential Seplling: I just couldnt see the method
And we've only been homeschooling for 2 years and that's all my fails so far! Hoping I hit the mark better for next year :/
