My sentimental and practical favorite is Robert Talbott. When I was much more conservative (and in conservative politics) many years ago, I wanted one of the classic regimentals which were a Talbott mainstay at the time - specifically a Royal Navy brigadier, navy and silver-white stripes on scarlet repp. A perfect tie for that business. (This was before I learned the etiquette rules regarding authentic regimentals, which I observe here in the USA even though they're technically in force only in Britain and her colonies.) That Talbott was (stay in your seats) $33.50 in 1989.
As both the brand and I have gotten older, I've come to appreciate their proprietary designs. As many of you have noted above about other designers, I like a few Talbott designs a lot more than the rest. As I'm an inveterate thrifter and eBayer (and used to haunt Nordie's Rack before and after the winter I worked there), I've seen and bought many of what I consider Talbott's best - and I've seen a ton of their misfires. (Bizarrely, I've rarely seen ties I consider attractive in their 7-fold line. I can't argue w/the construction of the 7-folds, but the patterns are usually neither elegant nor timeless. Honestly, they don't look good for the seasons they debut in.) I'm also not a fan of the Omaggio line, which may now be defunct.
Talbott's really improved quality - not in terms of construction, but richness of its silks, as well as some of the trimmings - over the years. I've got a couple of satin solids (from when those were a hot item) that can go toe to toe with their Brioni competitors. Their heavy wovens are amazing - rich colors and designs that tie a substantial, but not bloated knot. I do wish, however, that Talbott would do what many other premium makers have done - real keeper loops, maybe self-tipping, etc.
Also, they've flooded the market and cheapened the brand by shoving so much product out the door through the Rack stores at immediate, heavily-discounted prices. They've also started showing up at Marshall's. It's hard to justify a $125 full-retail price when they've got tons of stuff going straight to the Racks for $24.97/ea. with no intermediate stop at the main stores. It also seems that they're slapping the Best of Class labels on everything. It used to be that there was the base RT line, then the Studio line for trendier stuff, then the Best of Class for their top-shelf stuff like 40-ounce twills (this was long before Chelsea, Estate, and maybe even Seven Fold.) Now, the mid-grade lines are a muddled mess. I still love the brand, but they're pushing too much product out the door to do it as right as they used to.
I also enjoy Zegna (the brand Talbott wants to be), Hermes, Ferragamo, Ted Baker. I don't have Ike Behar, but love their ties - really most of the wovens and satins Superba (the licensee for Behar and Baker) makes. Up until a couple of years ago, Superba even made Merona (the Target house brand), and the ties looked like little brothers to the Behar and Baker models.
