Antler Peak, The ADK HH is a fine list. Their website has both a ADK HH and Catskill HH list. A NY HH list would cover the entire state in one list.

Summit post also has a NY 100 Highest list with some differences
from TR's list? Here's the link.

The short answer is different criteria.
As is stated on the Summit Post list, it was derived from the ADK 100 HH list (from the ADK guidebook) which has two criteria:
300' rise or 0.75 mile distance - for the 46
300' rise and 0.75 mile distance - for the remaining 54
and the Catskill 3500 Club list:
200' rise (the ADK guidebook states 250' or 0.50 mile distance which is from the club's bylaws, however, the actual list matches the standard 200' rise criteria, not the stated club bylaws criteria)
So the Summit Post list is based on a mix of 3 different criteria.
Tom's list is based on the NE 770 list (3000' peaks) which uses a 200' rise criteria. However, it grandfathers in the 46er peaks that do not have a 200' rise. Ideally these should be deleted from the NY HH list to maintain a consistent criteria. Both the Summit Post and Tom's list includes these:
Iroquois, Gray, Armstrong, Donaldson, Emmons, Nye
Note: Carson (South Dix), Dial - had a 200' rise on the 1950 maps, but are below 200' rise on the newer metric maps
Tom's list does have several Adirondack peaks which have a 200' rise, but less than 300' rise or were closer than 0.75 mile. Thus they are not on the Adirondack HH list nor the Summit Post list:
Table Top East Peak, Yard, McDonnel, Rist, Howard, Sawtooth wsw, Sawtooth sse
(Table Top East Peak has more than a 300' rise, but is only about 0.6 mile from Table Top)
There are also differences in elevations. The NE 770 and Tom used the more recent metric maps for the Adirondacks. The ADK 100 and Summit Post used the 1950 era maps with elevations in feet. I did notice that Tom used the 1950 era elevations for Couchsachraga and Hurricane.
So perhaps we still need a consensus NY HH list. IMO it should use a single and consistent criteria with no grandfathering. My personal preference would be for no distance criteria. There are several options on the rise. 300' would require dropping a very large number of 46er peaks, and some Catskill peaks. It may be better to use either a 200' rise, or the 160'
clean prominence used by the Peakbagger.com and Prominence groups. 160' clean prominence is equivalent to 200' rise where there are 40' contour lines (as on some White Mountain USGS quads), and it is a bit generous where there are 10 meter (328') contour lines in the Adirondacks. 160' clean prominence would also keep more Carson and Dial on the list. All of the Catskill Peaks in play for the NY HH list have 180' clean prominence, and no additional Catskill peaks come into play with a 160' clean prominence.
