I have a Surly and KHS, I like them both, mostly because of dropouts and tire clearences. Very basic and simple frames with no BLING, no fancy colours or labels to attract attention, and that's the way I like it. For me it's all about function, utility and simplicity. I think I'll be loyal to those two brands (frames) for a long time to come. I also like Salsa, Kona, Masi, because they still make frames with horizontal dropouts and track ends.
