Sharefest and google drive are made for different purposes.
Sharefest is a file sharing/transfer platform.
When Drive is, well as its name infers...a drive.
Yes, but it's much more limited by the inherent use of server storage. They, for instance, give 15GB (https://support.google.com/drive/answer/2736257?hl=en) for ALL your files. So you end up thinking, should I share via Drive and waste 10% of my space for this one time sharing.
