Hi, please add on to this list according to your knowledge/info. This is based on my reading and talking to salesperson.

1. Material:
Door:
Nyatoh - most expensive, last many many years, not very customizable depending on your company, usually small kitchen also more than rm10k

Melamine - least expensive, many choices of design, different thickness (different pricing/quality), least durable

Carcass: many types but recommended for aluminium for under sink

2. Hinges
Germany: Blum (most expensive, longest warranty) & Hafele (1-2 year warranty, has the slim drawer option unlike Blum)

China: no specific brand, mostly 1 year warranty

3. Accessories : refer above
German-made costs up to 3x compared to China made & can take on more weight on their drawers

4. Countertop
Marble: needs regular maintenance, most expensive, your malaysian cooking ingredients will seep through the top if u dont wipe quickly, can crack at the pattern area

Quartz: many different quality, most durable, least maintenance

Granite: needs maintenance, needs to wipe quickly when things spill.

Solid surface : more suitable for dry kitchen, can create seamless design with your sink

Please also recommend your KC companies if you've had good experience with them.
