IMHO Sugarloaf is the much better mountain. However, that early in the season, SR may have better coverage and more open since their snowmaking capacity is greater. If there is good early snow, though, SL would be my choice hands down.
So much depends on early season weather, though. I'd keep my options open until the last minute and see what happens. Finding lodging that early shouldn't be a problem at either place. I would also mention Saddleback, which is opening under new ownership this season with a great mountain, lower ticket prices and no crowds. But it is opening late this year - I think after the dates you mentioned.
