The first is the appearance. There is no doubt that the mini is smaller, and the difference is also said upstairs.

There is basically no difference in configuration, and it is also the CPU frequency of 434MHz, which is more sensitive than slim Mini;

In fact, mini is more expensive than 97, mainly because licensed products support 3G and WIFI, and the SPMark evaluation score of mini is higher than 97.

In other words, the mini is not just a reduction of the 97, but an adjustment and upgrade. Personally, I think it is worth starting.
