Which Pixel 7 is the best value?

I'm leaning towards the 7a.

Between the 7 and 7a, I'm just not seeing any meaningful differences that are worth the extra $100. The 7 Pro has some more concrete advantages, but are they truly worth the premium over the 7a? Do they improve the daily experience of the device enough?

Another advantage of the 7a is the longer support life. I think they are all technically the same length, but since they released 7a later, if you are buying a device today then the 7/7P will stop getting updates before the 7a does.

Thoughts? I'm using a Pixel 4a 5G right now, so that's my frame of reference. I'm perfectly happy with it, the upcoming end of life is what's pushing me to upgrade.
