I was expecting to have more ghosts on this list to be honest :P. Marshadow could have gone in fighting, freeing up space for another ghost, but it's my favorite Pokemon and favorite type so it deserved the ghost slot. :P
Looking over the list to see which gens I like most:
- Gen 1: 3 (not counting Alolan Raticate)
- contenders that didn't quite make it were
,
, 
- Gen 2: 0
and
were close for electric and bug, though. Also fond of
and
.
- Gen 3: 1
got beat out in its type slots, and I'm also fond of many from my original Ruby roster:
,
,
, 
- Gen 4: 2
, ,
,
, &
were other contenders
- Gen 5: 1 (not counting Galarian Darm)
- Gen 6: 3
- other contenders:
,
,
,
, 
- Gen 7: 4 (includes Alolan Raticate)
- other contenders include ,
, ,
,
,
, 
- Gen 8: 4 (includes Galarian Darmanitan)
- other contenders:
,

Evidently a bit of a bias toward later gens. A lot of that comes from these gens introducing more ghost types and regional forms. Possibly also because the older mons have had more time to ferment and fall in/out of favor.
