I'm going to buy a graphic theme, definitely, but I can not decide on Veronika, Alpha or Stela, they all have something that makes them very good, any recommendation for any of them ?, the main characteristics that interest me are the speed, which has search by Ajax in browser and mobile, good documentation and few errors in its current version. I have also bought the bussines plugin, so I would like to know the plugin coupling capacity with these themes.

@Xefiron
Decission is really up to you, choose what you prefer.
Business profile plugin will work with any theme.

In that case, could you tell me if the alpha theme has ajax search in its desktop and mobile version ?, and if it is positive, is it just text or does it also load the images of the item?

@Xefiron
Yes it has, test it by yourself:
https://alpha.mb-themes.com/search

It's that the option does not charge me, or maybe I'm making a mistake in the name. I upload you an example capture

Each theme is different has different features, what you show on stela is not available on alpha.

I understand, thank you very much for your answers
