Would you rather have a base Pixel 10 + Pixel 4 watch or a Pixel 9 pro and $200?

So I'm seeing the google fi deal to get the pixel 10 and pixel 4 watch for free with a new phone plan. I need a new phone plan, and my alternative is to bundle my home internet and phone for $40 a month (for first year) + $200 gift card. Doing the math, I save about $700 in cash going that route from what fi + my current internet cost. I could then buy a used pixel 9 pro online for about $500.

Pixel 9 pro seems more appealing to me because I want that better camera. But it would be used, and I'm not sure how the battery has been aging on these models. Plus, $200 extra dollars for whatever, and free next year to take advantage of the Black Friday deals that pop up then.

But with Pixel 10 deal I obviously get the new phone AND a new watch. I wouldn't do much with the watch besides use its health features. But still, two new devices. I consider the increased AI integration to be a downside and I would be locked in for 24 months.

If you were in my shoes, which offer would sound more attractive to you? Anything I'm probably not thinking about?
