It depends on your project preferences.
Neither machine excludes owning/using the other.
If you are doing a lot of edge to edge glue, like butcher block or laminated table tops, then a Jointer is the first piece of equipment.
If you are doing projects that require stock thicknesses, other than your local lumber yard supplied "nominal" thicknesses, the Thickness Planer will be your best first investment.
The Thickness Planers have their knives, pretty much, out of harms way and require "hearing protection" more than almost anything (always use eye protection - even with hand tools) else.
The JOINTER is very "different".
With the guard swung out of the way, while doing the actual edge or face jointing, up to the whole WIDTH of the revolving cutter head blades are exposed.
USE the push tools.
READ the Owner's manual.
NEVER talk to anyone else while you or they are using the Jointer tool.
This is a marvelously productive tool, that needs an incredible amount of respect while being used.
Oh, no "short" pieces on either a Jointer or Thickness planer.
"Bad things can happen" when machine processing short pieces.
Process long pieces and "cut" them shorter, later.
I hope this helps.
