You're far from the only one with that impression, the 29+ 120tpi version was intended to be as supple as a Racing Ralph Evo and is probably less durable (especially on the wide rims that expose the sidewalls more)

the wire bead 27tpi tires are more what you'd expect from Surly (and apparently the 26" 120tpi tire is like their previous ones too)
