    I’d go Mitsubishi. Mitsubishi and Daikin are the best in my opinion, with Mitsubishi being slightly better. For even money, I’d go Mitsubishi all day. Plus, if it’s an authorized diamond dealer - they halfway know what they’re talking about.

    The important question to ask isn't which brand is better but does either proposed 4 zone or 3 zone multi split makes sense.

    In almost all cases, these type of multi split setups (ie one head per room) are WAY oversized for the load they serve causing both energy efficiency and comfort issues.

    Multi splits are hard to get right, you have to do proper design up front, most important item is figure out what your heat and cooling loads actually are.

    Getting a proper manual J done (not by the contractor but by and HVAC designer) or at least a reasonable accurate one using one of the online calculators (loadcalc.net or coolcalc.com) is a good start.
