Since we have to use them in the first place, I have found that there is a HUGE difference in brands and varieties within the same brand.  Trojan Maxums are total deal breakers for me.  I think they are the red packaged ones.  They are such that I can hardly wait to get out of them.  I have no experience (that I know of) with FC's.  But then I know they may have been used in some of my experiences in addition to a MC when I was unaware of why they didn't want any digital penetration.  I know I have found a number of things in there.  It is not unusual for a lady to use a sponge so she can keep working during her time of the month. I find that very rude and also very greedy.  One time I found a diamond ring up there.  When I retrieved it the lady thanked me and said she couldn't remember where she left her wedding ring. Just kidding about that.  

For me, the best with the most sensation is the Trojan Ultra Thin.  It is clear in color and allows for significant pleasure.  They are the ones in the blue/gray package.  AS far as the people who are alergic to latex are concerned (both men and women), I have experienced Durex Avanti SuperThin.  They also allow for good sensitivity.  But to each his own.  In other words, don't use one that someone else has already used.lol.
