The iPad line is a bit of a mess at the moment.
If I could wave my magic wand there would be just three basic models: iPad Mini, iPad 11, iPad 12.9, but with a few more configuration options, perhaps processing power and type of camera unit if Apple want to upsell a 'pro' config to resist putting their latest CPU / camera on the basic model.
The range could then share a consistent aesthetic and basic feature set (e.g. USB-C, FaceID, thin bezel design, pro-motion display, etc.) instead of the crazy mix you have now.
I love my new iPad Mini in use, but it looks identical to the 2012 model and the bezels seriously date it. How is Apple, a design leader, still selling an 8 year old design?
Still, OP should just pony up for the 11 (or wait a few weeks if rumours are true of new models).
