kenwood is 1.5 juta?

If bake cake only, then kitchen aid. If you want to knead dough, kenwood better. But then kenwood is fugly. If buy kenwood, one need to figure out how to hide the mixer.

Can also. But then you cannot do anything else while mixing the batter if you use hand mixer. I use stand mixer + hand blender (for beating egg white) to multitask while baking.

If you only bake once in a while, hand mixer should be fine. But if you bake once a week or more often, you should invest in a good stand mixer. Stand mixer other than kenwood & kitchen aid also fine if only for baking cake. You don’t need powerful motor for creaming butter or whipping cream or egg whites.

Powerful motor is only needed when kneading dough.

Use to be sold in Malaysia. But then kitchenaid dominated the aesthetic market. So they only sell the ugly kenwood to people who actually want to bake not take picture
