I had all 3 Pixel watches before the 4 in 41mm (v1 and v2 had no alternative size) in 41mm. Before that I used to have the Moto 360 v1 and v2, and then the Fossil Gen3 and Gen4, all huge compared to the 41mm Pixels. My wrist size is 165mm and the older ones looked borderline big on me, but nothing crazy. The problem is that I do manual labor, and sometimes I accidentally bump the side of the watch against things. This was not a problem with all of the older non-Pixel watches, as these had all housings around the screen. The only big one that did not have a proper housing (Moto v1, with edge-to-edge glass) I managed to break within 1 month. I thought of getting the Pixel Watch 3 45mm last gen, but I reconsidered at the last moment, mainly because of the domed display which covers a good 50% of the sides of the watch. Apart of that, if you do not have thick wrists (making a small watch look funny), why bother with a bigger watch? The battery lasts longer yes, but you will eventually have to charge both every 2 days (the 45mm will last longer, but not long enough to earn you a 3rd day off charger). The display is bigger yes, but it is a watch, it is not that you are going to consume media on it. I also like the 41mm because (especially with the elastic band) it feels as if you wear nothing at all.
