Hello Vikalp, First of all welcome!
One big differentiating factor of ZFS is its comparatively much more complex and thus longer mount process. See e.g. [1] for a chart comparing mount times on OSv. More generally, we should bear in mind that ZFS if feature-full and most importantly, it is read-write, whereas *ROFS is read-only*. This allows it to optimize better for its use case. Waldek, as the author of ROFS, might have more insight into this.
