Top & Base coat comparison: OPI vs Revlon's

At the moment these are the two brands of top and base coats I am using.
I thought I'd do a comparison of the two: Revlon's colour stay base and top coat (seperate) and OPI's 3 in 1 top, base and strengthener.
In Aus the OPi polish is priced $24.90 and each of the Revlon's about $15 and although I expected OPi to have the lead in which polish I prefer I actually must say that I prefer Revlon out of these options.
The OPI t&b although works well with the OPI formular, I found to be very tricky to apply, especially with darker colours. I found that even when I waited for my colours to dry completely, that the brush would still take some of the colour with it when applying the top coat. Definitely a bad point for me as as you can tell, especially after using deep reds, the clearness of the polish begins to fad.

Revlon on the other hand I found to be way better than I expected. I haven't tried the non colour stay variety of the t&b but the colour stay ones were amazing. I found them to work best with Revlon of course but they still performed really well with alternate brands. And if you are not familiar with the colourstay brush it was amazing to use, so easy! It's like 2 brushes in 1!
I am actually really impressed with the colourstay line Revlon has put out. Thumbs up Yey!
Just quickly, I found the Revlon base coat to be so much thicker and more protective than the OPI duo. Although this could be due to the fact that the OPI one is in a duo, but I found that I've started just using the OPI as a top and not a base coat at all as I prefer the Revlon base by far.
So basically if you want to find a cheaper alternate for a top and base coat(and I know in the states it's a lot cheaper), give the Revlon colourstay polishes ago :)
