I think it's personal choice really. I prefer older/vintage Chanel flaps & totes to new. One, I think the quality of new has gone downhill versus old. Chanel used to be made to last a lifetime. You can search this forum and read for yourself. I also prefer the different patterns of stitching (chevron, lines, diagonal) of pre-karl Chanel and, lastly, love the huge CC on the classic flap.
What I like about new? the colors. Otherwise I'm happy buying vintage/older Chanels.
