I didn’t think any of those are the base model. Anything with Pro or Ultra in the name should have more than 8Gb of RAM in my opinion. It also seems dominated by OnePlus as the others listed are not really players in the larger market. You could possibly argue that Xaomi is but I’ve never even seen one of these phones in the real world. In fact it looks like most of these are only available in China variant.

I am writing this using my Xiaomi poco x3 pro, although it have 8gb ram and 256gb memory, it also have headphone jack and micro SD slot
