Nowadays not many look at brands but price. For >500L capacity, the Chinese brands are far cheaper. Hisense 550L is about RM2k or slightly more only. Other brands around 5k+. A relative bought one earlier last year. So cheap, can change every 2 years but I presume they will last longer.

Based on my experience, I would advise that you plan carefully and if possible, get the largest capacity fridge which you can accommodate as you would never know. I was previously in your position as I bought a smaller capacity fridge (350L) based on the available space although I could actually accommodate a bigger capacity one with better optimisation of the space ie. other rack or furniture arranged properly to allow placement of a larger fridge. After living with the fridge for several years, our family figured out it's too small as we can't buy too many things or else it would be packed full, especially vegetables, fruits and other food stuff. It's better to have more available space rather than limited space. Electricity consumption may be slightly higher but in terms of convenience it is way ahead, and to me convenience takes precedence over everything else.

The design of the fridge whether it's 2 doors, 4 doors, bottom freezer, top freezer or side freezer, that's up to individual preference and I have no comment on that.
