Ive used ratcheting crimpers before, but only on antenna connections- Never on wire.
I almost feel disconnected when using them.. Can't really tell how much pressure you have...
I use a set like the 2nd link- the channellocks. Mine are Kleins, got them at Home Depot for around $20- works great.
With those connectors, I'd use those little tabs as more as something to hold the insulation on the wire IN the connector & less for crimping to the wire...
I would solder the wires to the connector & bend those tabs over to hold the wire. You could use anything for that.
