one note of importance: lower-priced (maybe higher priced as well) ratcheting crimpers are almost always designed for insulated crimps/terminals. They won't get tight enough on a bare terminal/crimp
and if you plan to use your own heat shrink (or adhesive lined shrink) then you probably want bare terminals
I discovered this after doing a really good job on re-wiring an area behind the dash of my truck. Many (many!) of the crimps failed, and with some investigation it is clear that it is because the crimper assumes a thin layer of plastic (the insulation) on insulated crimps. Without that extra layer, they don't get tight enough.
So while a ratcheting tool is the "better" option, it is not foolproof nor perfect. Just my 2 cents.
