VHS was inferior to LaserDisc, enough said about that. As for the pros of VHS:
-Cheaper
-Much more easily accessible, seen in more stores
-Simpler in operation
Laserdisc pros (some of these I may pull out of my ass, please PLEASE correct me):
-Analog encode, like a record; meaning no compression.
-Less chance of wearing it out, however a chance they could warp.
-Multiple audio tracks
Laserdisc was never really "put out there" though, and was a niche machine for videophiles only. In Japan, the machine was popular though. Many anime got very good Laserdisc releases, including occasionally in the US here (I recall Tenchi Muyo being available in the format). If anything, laserdiscs were just inconvenient; the size of vinyl records, which made it less easy to store.
I hope my limited knowledge is of some use!
