Totally agree with this. I have two Evie 29’s and a Bolide 31 and love them all to bits.I also love my Evie and was thinking about buying a 2nd or a Jypsiere last year. Here's my $.02... I decided against the J because it was a lot of money for the same functionality as the Evie - though of course it is more formal and might be more appropriate for work or something like that. I just didn't think it was different enough of a bag to spend the extra premium on. But I DID still want something more formal than the Evie for work, nicer shopping trips, etc and rather than the J ended up with the Bolide. It can't be worn crossbody so not a proxy for J but my point is I think you should look to a bag that gives you the same functionality as E/J but also offers something different.
If it's just these 2, I'd go Evie. Nicer price point and you can get a fun color without feeling limited to how you wear it. I almost exclusively wear my Evie too so I totally get owning them in multiple colors!
OP, I’ve looked into the J a few times and I LOVE the look of it, but the opening is too annoying for me.
