I install these types of systems in peoples houses on occasion and just finished one 4 head 36000btu system which worked well through last winter heating while we worked on the radiant floor retrofit. The thing to remember is that the efficiency of multi-head units is not as good as the single head ones. For example, you can get a Fujitsu single head 18000btu unit with a seer rating of 27 but the 3 head unit seer ratings vary from 16 to 21. Still good but not quite as good.
That said, the customers said that they were very comfortable last winter (very cold one too). There was 3 heads on the 2nd fl and 1 larger one on the main fl.
