The person who you spoke to clearly had little knowledge of math programs. I do agree that Saxon math is not very good. It is especially bad for gifted children. Everyday Math is often held out as an example of a bad math program. It has even been in the news it is so bad.
Singapore Math, the US Edition, is exactly the same as Singapore Math the 3rd edition (non-US edition) except that the US edition has some added chapters to cover US measurements. If you go to the Singapore Math website, it shows you exactly where the differences are. I use Singapore Math and have both editions. Page for page, the books are exactly the same, with the exception of some Americanized names and the added chapters. Nothing has been removed for the US editions from the 3rd edition.
Dr Winningham was clearly pushing Everyday Math because she works for the place that makes it. Think of her as the advertiser. She is working for the company that produces that product. You would be making a huge mistake if you bought in to this.
I am not familiar with Trailblazers.
