Is Falling Bash actually better than Jump Slash for mounting?

Mounting a monster has undergone a major revamp in MONSTER HUNTER RISE, and so has the Sword and Shield’s moveset. In it, Falling Bash is now treated as an aerial move and can be used to mount a monster.

So, does it mean now the jumping slash is obsolete? Damage of Jump Slash is pathetic compared to Falling Bash. Does it mean the Falling Bash is actually better in all aspects, especially mounting since it is significantly stronger than the jumping slash?
