Borrelli: I have over a dozen now:
For colors/patterns, width, quality. Just amazing ties. Some great blends of color. I do prefer their thicker twills, 7 folds, and their cashmere and blends are nice in fall winter with flannel suits.
Ties in an almost grenadine are just amazing, really amazing, very classy patterns and rich.
For colors, very understated yet rich.
I've tried Kiton, Brioni, Charvet but I can't say I care for their colors, patterns and Kiton's width is a tad to slim for my lapels usually.
I'll give Charvet the point that they do look rich, luxurious, I just don't care for their patterns very much or there is just something about them I just don't like. But I haven't really studied them as I'm not drawn to them.
The worst ties are RLPL, god they are just plain awful for what they charge once you try some of the above. Canali makes some nice patterns but they just arn't near the level of quality of the above. And their dress shirts are horrible.
