No real difference, so easier to just buy local. Lol

Female condoms aren't always best for younger men, and...  there's definitely a contingent of men who turn down female condoms and seem quick to flush the one they do use.  

I never learned the mouth method...

the original scared me from trying them for so long because they smelled weird, felt REALLY weird(like I had shoved a plastic bag up my cooch), and made the strangest noises much like the russling of said plastic bag as well as sqeeking noises.  It was actually quite mortifying and after that "trial" run I HATED the original Female Condoms.

Now, because FC2 were becoming so popular I read up and found they were different and much improved so then started the learning curve on how I could make them work.  Still perfecting since I find that I usually end up putting too much lube inside so it ends up slooshing out onto my thighs, but hey, better too much then too little.  

Now, I love them and try to use them with most of my guests.  There are some I will not use them with because I worry if the guest is too long and might try to pull it in or very small and will be unable to feel anything.  It does cut down on bad friction and "drag" and lighting lubing the outside gives me enough of the good friction that I can still achieve with no issues.  But it is hard to figure out how it might work for you, and yes, I leave the ring in to anchor it inside.  Without that it is just a loose condom...

Goto run, but glad I got to figure out how to best make them work for me
