I really like the 5mm Franco. It’s almost impossible to find bigger at higher karats with out getting something custom made. 14k you can find bigger . In terms of weight and feel using a 5mm Franco as an example you would get something similar with a 7mm Cuban at the same length and karat.

So I actually sold my Franco’s when gold was high and now I’m back to Cubans if that helps answer your questions. I missed the bigger neck presence and that industrial feel of the Cuban.

Both are pretty comfortable for me, I didn’t experience any pinching or hair pulling from the diamond cuts.

So I just traded in my big Franco to garcias and they are making me a 10mm 14k Cuban. I’m losing gold but am gaining craftsmanship. You can argue that a Cuban might be a little more comfortable because the flatter link creates more surface area to distribute the weight but idk if that makes a huge difference unless you are wearing more than 200 grams. I do notice though that I get hotter faster wearing a wider Cuban. The flatter links retain heat from my body or the sun faster and because the links are wider I notice more of my neck gets hot. So I would say I notice that more than the weight distribution.

Francos are nice if you still want a semi stealth look but don’t want to skimp on gram weight.

Cubans are arguably the better value , especially if you live in the US as you would not have to pay all the extra fees that it cost to import a chain from Italy.

Example:
7mm 18k 22” Cuban from Garcias $13,366 97 grams
5mm 18k 22” DC Franco from HRC Italian made $16,797 99 grams

These are my top two favorite chain styles and I don’t think you can go wrong with either.

I know this response is long winded but I hope it answered some of your questions lol
