Hi, we've started with ESF gymnastics and liking it so far. My 5yo has been with MyGym for many years, so i thot she'd be quite advanced. But at ESF, she got grouped with the younger kids, coz the older group has graduated from a year with ESF gymnastics last year. I thought it'd be too boring for her, but I can understand why, ESF is more strict at trying to get the basic postures right. while MyGym do more fun stuff, some quite challenging already, they are not as strict with the basics. E.g. ESF will want them to get even a froggy jump right before letting you move on. My girl seems to understand that too and was not complaining, so going well so far.
