Your statement about the 97-99 heads is true.
I guess it would depend on your intentions for either pair of heads.
96 25D HLA heads for the smoothness/quickness of response or the 97-99 heads for a slightly longer powerband for touring/long distance traveling. The 97-99 25D heads on my 22E come to life after about 2500rpm & the power is carried all the way to redline.
