MSR has a venerable reputation and there are extremely few tents out there that offer snow flaps, which are extraordinarily effective anchoring devices.

Mountain Hardwear, with a less stellar but still good reputation, briefly offered snow flaps on its Kiva model. The current version doesn't offer snow flaps

Kiva, which due to its higher profile, larger size and single rather than double poles, is almost surely less stable in wind than MSR TS, but is nonetheless advertised as a "winter mountaineering shelter," though it's listed on MH's "superlight" rather than "expedition" page.

I'd say both these tents are reasonably described by their makers.
