Celine Mini 16 vs. Gucci 1955 Horsebit

I'm considering getting the Celine Mini 16 or the Gucci 1955 Horsebit shoulder bag and am torn between them. Does anyone have experience with these bags, either seeing them in person or owning them? How do you like them, how did they hold up, and how practical are they to use/carry?

I am also looking for a bag that has staying power, so curious whether these are classics or whether one/both are likely to go out of style.

Thanks in advance!
