aw s7 45mm stainless and steel silicone strap vs aw s7 41mm stainless steel and milano steel strap vs aw s9 44mm aluminium.
Which one would you choose? They’re all pretty much the same price.
Whatever Apple Watch you like the best is fine.
Personally I would get the Apple Watch Series 9 Aluminum 45mm if I could afford it.
The s9 has a better chip and more pixels on the screen. You can always get another band. I have the seven and am holding on until a Continuous Glucose Monitor comes on board.
The differences in the SS models come down to size, not band. Bands are replaceable. Get the size that makes you happy 41 or 45mm. Me? I’d get the SS. They have sapphire glass faces which are far more resistant to scratches, and the SS body itself (plain SS, not colored like graphite) can also be polished if scratched up.
S7 vs S9? The differences are incremental. The comparison is more if the S7 is new in box to new S9. If it’s a used or refurbished S7 (unless from Apple directly, as their refurbs are like new with a fresh battery and unmarked body and face) to a new S9, consider things like battery health and presence or absence of a warranty to make a more informed decision.
Whatever suits you , the SS looks more formal depending on how you dress
