I use both for commuting duty. The lht is geared, while the crosscheck is not. All in all, I'd say the crosscheck is the more fun to ride. It's lighter and more nimble as stated above. It is also the more versatile of the two, which is why it was the first Surly bike in my collection. It's had flat bars, mustache bars. and all manner of drop bars. Single speed, geared, it does all with equal aplomb. If I could only have one bike, it would be my crosscheck.
