MKBHD says to get the 8 over the 8a but I disagree. The improvements are marginal. Unless you really need wireless power sharing, the 8a offers pretty much everything the 8 does if slightly slower.
Best Buy gift card + trade-in or waiting till a price drop make it more enticing than paying $500 for the Pixel 8.
I’m plenty happy with my 6a so I’m going to hold onto it.
