Yea, that the only direction to go. Start with what you think is the best and then move to what's right for you. Also, the old summicrons hold their value (as most classic lenses these days regardless of mfg) so buying and selling used has little monetary risk when your trying to find what's right for you. I wouldn't know about Madison Avenue hype or test charts regarding the CV or Summicrons, but human psyc and phenomenology regarding GAS I have some experience.
