Hi.  I own four Revlon ones and one L'Oreal.  In Revlon I have the red, berry, pink and bronze colors (Sorry I don't remember the names.)  In L'Oreal, just the light pink one.  In my experience the Revlon ones are super pigmented, almost like a lipstick, with the texture of a balm.  L'Oreal's is virtually invisible, kind of like a tinted chapstick or those new lip smacker psuedo balms from Maybelline.

My favorite Revlon is the beigey bronze one, (maybe Creme Brulee is the name).  It's my favorite neutral lip to keep in my purse for everyday wear.  The Red is an almost too intense red on me, but it probably works for those with warmer/darker coloring.  If you own any of Poppy Lipstick Queen lipsticks like Midevil, the Revlon butters show up way more than those lipsticks as a comparison.

Hope this helps.

Thanks for the help! I picked up one of the Revon lip butters today, which I got on a great sale. It is really pigmented, which I like, but I already have so many lipsticks, I think I will just stick with the one for now. 

It depends on how much color you want on your lips.  Le Balm is sheer but it's buildable.  Lip Butter has slightly more pigments, which almost mimick a sheer lipstick.  At the moment, I have Le Balm in Nourishing Nude and Lip Butter in Pink Truffle.  I wasn't sure how the color payoff was going to be at the time I purchased it so I went for natural looking colors.  Nourshing Nude is exactly like my lip color but better so I'm able to apply it without a mirror.  I use Pink Truffle for going out since it has more color to it.  I like to play up my eyes more so I stay with a neutral lip. 

Hope this helps.
