Out of Gillette, Venus, isana and Nivea which of them gives the most coverage and volume? I only tried Venus and it's way to "watery" and and just doesn't cover you good.

I've seen that barbasol is really nice but unfortunately they don't sell it in my country

Best option is to buy a can of each and try them yourself.

Not only for consistency, but also for your skin/eye/mouth sensitivity to each. I have found that different brands bother different people (and even variants within a brand).
