my wrist a bit small. now using S4 44mm. i buy this ultra, will it be like hippo on my wrist?

I've been considering purchasing an AWU for my next smartwatch, but I've noticed in the Facebook Apple Watch group there seems to be a lot of sellers offering this model compared to the S8. Is there a reason for this? I have a small wrist and currently use the 44mm S4, so I'm wondering if there are any sizing or other issues with the AWU I should be aware of before making a purchase. Would love to hear opinions from the community. Thank you!
