I'm a T206 portrait fan. I prefer the simple, clean design with many classic Horner portraits turned into those very detailed images. T205 loses me because the portraits are not as detailed and for its approach to each league. The cards from the AL, NL and ML all look like they are from different sets. I also find the color borders distracting. My preference over T207 would be the end panels from T202s (which i think are the most interesting T designs of all):
As for N cards foretelling modern cards, The N269 Lorillard set is one I enjoy because the cards are roughly modern in dimensions and have bio backs
