6a more recent and has the same spec as the 6, but the 6a is made of plastic and doesn't have a 120hz screen. I had a 6a to dip me toe in. It is a piece of plastic though so feels cheap 🤣 get the standard 6 the price difference will be minimal if any.  

 Or 6 pro only if you need a bigger phone  

 That’s good to know. Thanks! 

 Ah so 6a is plastic 

 Yeah if coming from an iPhone it feels like a toy.  

 Definitely. I would be afraid to drop it
