Question Which Android TV without certification should I buy to use with Kodi ?

Hi everyone,

I want to buy an Android TV to use Kodi and which can be used to browse online, youtube, mmovies, etc. I'm not so interested in watching movies with it. There are a few models I have taken an interest in:

Mecool KM6 Deluxe
A95X F4
X88 pro 10
X99 Max +
Vontar X3

What can you tell me about these Android TVs ? I don't want to buy one which is too expensive and has more than I will require. I would really appreciate your help.
