Landscape architecture is better, of course! Kidding aside, Kansas State was set up such that all design disciplines went through the same first year program. Toward the end, each college pitched their program to the 1st year students and we headed off down our respective paths. I presume that most schools do this, but if a school has a strong program in only one or the other then I understand your asking now.
BTW, one of the greatest attributes of Landscape Architecture is its diversity. Not all of us end up in the niche we thought we would, but have a fulfilling career. Salaries probably vary much more than in Architecture thanks to the diversity of work. Good luck whichever you choose,
