I'm a solid pantser. Tried outlining and it never worked. Everything I've done I've done this way. Considering my "Dead Souls Doing the Samba" has been optioned for a screenplay and someone's asked about Bright Morn for TV (not holding out any hope there) I think I'm doing ok. I earned my living writing for audio drama for 12 years as a pantser and have worked on many other things (all of which I got paid for), all of it being done as a pantser this is the way that works best for me.
I truly think everyone should find what works best for them, that's done through trial and error. Pantsing isn't for everyone, although I'm always tickled to find out both Stephen King and Margaret Atwood (Handmaiden's Tale) are both pantsers, as is mystery writer J.A. Jance. I think they've all done alright in their careers. And lets not forget Deane Koontz, Ray Bradbury and Nora Roberts.
I also think that sometimes, if a person has been working long enough and done enough different things (plays, screenplays, articles, short stories, even limericks) you develop an inner plot that you occasionally consult... or kick to the curd depending on the fuel you're using (coffee, wine, tepid tea).
It all boils down to: write the way that works the best for you.
