Little Otter vs other online therapy options for kids

I am trying to understand how pediatric online therapy options differ because a lot of the websites start to sound the same from the outside. Emora Health, Brightline, Talkspace, Amwell and Thriveworks are the ones Im comparing right now, but the care models seem pretty different depending on age, parent involvement, insurance, psychiatry access and whether the therapist really works with kids or mostly teens. I care most about fit for younger children, how involved parents are in sessions and how quickly care can start. For people who know this space, what should parents compare first when looking at Little Otter alternatives or similar services?
