The 753 was a bit too much but the 200 model was a perfect sized frame IMO.
I think the 753 would have been more popular had it been introduced earlier in the 757 program. It's a good DC-10 short-to-midhaul replacement and probably would have been more popular with both American and European airlines had it been introduced about five to ten years earlier than it was. By the time it was introduced, the 757 program was starting to wind down and so airlines just weren't into it.

You forget that the NEO will eventually be TATL capable (well before 757 retirement) so the few 757 TATL routes are a non-issue.
The whole point between the 321NEO is that it is not quite as capable as the 757. Combined with a newer overall design and brand-spanking-new engines, that gives it a huge efficiency boost. Whether it can do TATL routes is a function of payload. Remember, adding range to an aircraft usually means that you need to add weight. Basic physics dictate that an aircraft becomes less efficient the shorter the route it flies as a percentage of max range.
Also, the payload-range charts are above. As you move to the rightward end of the chart, you see that the 757 carries ~5,000 more kg than the -321NEO for a given mission distance. From EWR
at ~3500NM, the -321NEO carries ~17,500kg and the 752 carries ~22,500kg. That's a huge difference. That puts you on the steep part of the -NEO's payload-range chart and on the gentle part of the 757's curve. But EWR
is one of the shortest nonstop TATL routes there is. By the time you want to fly to CDG
, your payload is down to ~13,000kg. And remember, a good ~2000kg of payload are already used on crew, interior fittings, catering, drinking/wash/lav water, etc.
If the -NEO becomes TATL-capable, it will be due to rightward shift of the payload-range curve as the engines get more efficient, but it will never have quite the oomph of the 752.

You make the same mistake as all others, a derivative of the 752 will expand beyond TATL, it will be more capable.
Then I am making the same mistake as every single airline in the world. And I promise that they know more about aviation than either you or I.
