I'd say yes on the Mr. Gator Gang as a daily bag. Especially if you close the bottom zipper, it becomes a fairly slim profile bag that is perfect for a casual daily use. I can't compare directly, but I'd say it's smaller than Arayla's Hepburn by my memory. I am not sure if the Mini would fit a laptop? You can always ask DP themselves, they are pretty responsive to emails during weekdays (of course keeping in mind a huge time zone difference vs the States).
@southernbelle43 and I traded some bags back in the day and I had her Mr Fill and Zip medium size. It was a great bag that I ended up gifting to a relative, and I occasionally still miss it lol. If there were 2 things I'd change about DP overall, it would be
1. Strap drop. They tend to be in a "neither here nor there" territory of length for me. Meaning, on a Mr. Gator Gang the long strap is much too short to wear crossbody, but too long for a shoulder carry of my liking. It might be my gait, but bags tend to bounce about on my shoulder if not secured by an elbow and I can't STAND the feeling of a bag sliding off (first world problems, I know). So with this bag I mostly end up carrying it on my shoulder with the top straps, which are a tad shorter than my normal preferred strap drop of about 10-11 inches. Alternatively, I wear it as a super short crossbody by swinging the bag on my back if I am just walking somewhere for a bit. It's really not that big of a deal, but something to consider if those things bother you.
2. Their lining is a super utilitarian black fabric - I wish they would use other colors for better visibility. It is very similar to Balenciaga linings in that regard.
All that being said, both of my DP bags, Mr. Mini Armadillo and Mr. Gator Gang, are most definitely among huge favorites due to their versatility, leather quality, and overall excellent construction and style

. If you end up getting one of their bags, do make sure to use a 10% off code, it goes a long way with more expensive models.
