Comparison of charge transfer energy according to SAPT0 with NBO

In general, no. They are differently defined.
The difficulty lies in the fact that CT is well understood as a chemical concept, but poorly defined as a physical/mathematical term.
Thus CT among EDA schemes is very difficult to compare with each and can even be different by an order of magnitude (I dont find the paper that nicely showed this).

Some starting points for reading:

for SAPT vs NBO explicitly: https://pubs.acs.org/doi/10.1021/acs.jpca.6b12930; https://pubs.acs.org/doi/10.1021/acs.jpca.7b08165
