@MasersI think if your child is math-oriented TGATB would be ok. It definitely has more review than MLFLE, which I feel jumps around every other page. I do think both curriculums are good about using hands-on materials. TGATB has longer lessons (though, again, they are shortening them in the new version, I believe). TGATB is very manipulative heavy, and I found it a chore to put everything together for the next day, whereas MLFLE is pretty open and go. Between the two, however, I would definitely go with TGATB as it seems more focused and comprehensive.
I do like Kate Snow's K program. I like that she doesn't have a lot of written work (my son is slow in handwriting), and that it includes review daily as well as a lot of hands-on activities. They are not long lessons, either, which helps with an antsy boy. I am pretty sure I am going to stick with the program as I believe in the mantra "if it isn't broke, don't fix it." My son is more math-minded, however, so the concepts come easily to him regardless of the method. However, I do think another program with lots of worksheets would kill him 😛
