Which is the best application for editing Instagram Reels or YouTube Shorts?

For my short video content, I generally use Capcut, which helps me in editing trending videos and audios, adding auto effects and auto captions. But it doesn’t let me stack multiple videos at once. I want to grow my viewers on Reels or Shorts. Suggest a few more best applications, as my content demands high-quality editing tools. My bio is a food blogger where I showcase my food recipes.
