The only issue with some of the options you listed is that you are to close to blow up some wakeups (like lightning hands, jokers flower, etc.) They will beat you with invinci and blow you up.
With the Hot Sauce setup, you are literally put in that magic range where those moves whiff, and if hit, the opponent is still in range for a full combo punish.
I use 1~pound against a lot of characters that have wakeups with little to no range (Lightning Cage, WW Spin, etc.) The hot sauce however, covers the jumps, the backdashes, the forward dashes, and all other options.
Raven has little to no invincibility. Staff Spin and 2 will still get beat by moves that are true wakeups. (Batgirls cartwheel, Lanterns Might, Rising grab, MB cleaver, Arachnid, etc.)
