Oh that's really interesting. I watched a razr and Z comparison video and the razr looked like it came out on top to me as well, though no judgment was made by the video.
I have the 2022 razr model. Which has a slightly different form factor than the newer models might have worked better for me. Larger bezels are a bit easier for me to use. As for feeling bulky no not at all. It felt a very nice and good size for one hand when folded. Then when unfolded it felt like a normal phone.
As for the pixel fold well. Folded it feels like a heavy and slightly bulky normal phone. Which is fine. Actually, I don't mind the heaviness of it or the bulkiness of it. That said, I have a lot of problems with the phone's design. For instance, the heaviness makes it difficult to handle confidently without pressing a button for me.
