there are countless decent android tablet not from Samsung. Lenovo, oppo, oneplus, xiaomi.

Oppo is Chinese, so is Oneplus, so is Xiaomi - those are what I meant with "alibaba garbage", especially when it comes to performance. I don't trust either of these brands to deliver updates on time or for more than two years, spare parts just the same, and that's before the question if one wants a brand that may be targeted by US sanctions like Huawei, locking the user out of Play Services.

With Samsung there are established networks on how to get spare parts and they have a proven track record of delivering updates on time.

Lenovo's offerings are a disaster performance-wise.
