Sulphur-breasted Warbler or Goodson's?

Is the wing bar useful to distinguish these two species??? Thanks for help.

I'm not sure because I currently don't have my guide with me, but according to some photos I found, I saw that both had to wing bars, but in Sulphur breasted warblers, one is less prominent and almost invisible, whereas Goodson's has two obvious wing bars. Because of this, I'm guessing Goodson's, but I'm not a professional, I'm not really sure, can anyone else help?

The head pattern is useful for these. On Sulphur-breasted, the dark eyestripe and sides to the crown are black, but on Goodson's are dark green. On the first photo you can see that these look green, suggesting that this is a Goodson's. I think also that Sulphur-breasted would be stronger and brighter yellow on the underparts, whereas this bird is slightly duller yellow and is paler on the flanks.
