Which Xtrons? Sorry!

Ok, have a couple of bottles of wine and now have a fine wee dram beside me while looking for an Android double DIN headunit. My ZT did originally come with the high line setup but it died before I got it so currently has a single DIN kenwood HU. The wiring appears to be all there in the boot still, fairly mucky looming tbh but do I really need it now?
I was thinking of getting one of the 3 linked below but what am I losing out with on the cheapest one here

And then between these two at the same price, what’s the Best Buy?

I am at the moment personally preferring the last one but is that because I am slightly inebriated?
As I currently have a single DIN HU do I need any xablenadaptors?
I would be adding a mic and DAB as extras but think that then covers everything I want, am I missing anything obvious here?
Cheers much for any help or pointers
