I was lying in bed the other night thinking about lipstick, as you do and came across this dupe for my newest MAC lipstick Watch Me Simmer! It is pretty much identical with the only visual difference being the finish as my dupe for it is Revlon's Matte lipstick in Pink About It.
Now I believe that Pink About It is a limited edition shade but it is pretty easily found on eBay for a few pounds so thought this was worth mentioning!
Both shades are a pretty corally pink colour with the MAC one showing up slightly brighter because of the sheen it has. I think I actually prefer the Revlon lipstick actually, I'm not usually a fan on matt finishes but somehow Revlon seem to make it work for me. If you want a finish that looks the same as MACs creamsheen then adding a bit of lip balm into the mix will give it a nice sheen if matt isn't your thing.
The scents are different too with MAC being a light vanilla scent and the Revlon pretty scentless. I always prefer an un perfumed lipstick over a scented one anyway! They are both pretty highly pigmented with MAC slightly taking the lead because of the creamier formula.
Both are pretty sturdy packaging wise with Watch Me Simmer being slightly more compact but when it comes to lipstick, I'm not overly fussy about what the tube looks like usually. Price wise, seeing as you can pick the Revlon Lipstick up off eBay for a about £3 there is a good £10 difference which is a pretty brilliant saving! I have checked eBay and currently there are plenty available!
