for wallets/SLGs, Taiga is the best for me. the leather is heard-wearing, doesn't scratch easily and water resistant. Damier Graphite would be my second choice. but if its only for looks, Monogram Glacé is still tops.
I like a few of them, I really like the Utah leather in coffee best and recently bought my DH a wallet in Damier ebene so I like that as well. I also like the Taiga, but my DH did not! The Utah and Taiga are my favorites!
Ugh, how boring!!! Get an epi zippy in black or mono if you can't handle any color. Nothing is more boring then LV men's wallets. I'm a guy and there is nothing better then zippy wallets to hold all of your crap.
I guess it depends on a style. Damier Ebene (darker shade) or Graphite for compact wallets and Taiga Grizzli or Gray for compact and long wallets. I like the Utah Coffee too. Black Epi simple card holder is also nice.
Right now, I use a Damier Ebene (lighter brown) wallet and a Damier Ebene (darker brown) simple card holder. They are all right I guess.
