We summited via Main Trail on 15 of Feb. The weather and snow conditions were just perfect. We were the only team which reached the summit that day and (perhaps) first after the storms. I met other party who summited via MR.
Snow basically starts just before Outpost Camp. Snow in the gully below Trail Crest is "easy" to climb (many footsteps) and to glissade, and the snow path on the ridge has solid footsteps now as well. However, I would strongly recommend crampons, an ice axe and a helmet (micro-spikes would work too). No snowshoes needed; unless, someone would prefer cross-country.
