Picsart is a great option if you're looking for some quirky editing features. For more classic features and presets, you could try either Lightroom, VSCO or Snapseed.
VSCO or Adobe Lightroom are super
I use PicsArt and snapseed. They are easy to use and does wonder to the pictures . Although it depends upon ones skill how much he/she is good and creative about editing
Snapseed and vsco are the best ones. Phone version of Lightroom is another great way to go.
I use Snapseed and Photogrid!
