It depends on the yeast strain. Some liquid yeast strains will give you 80% or attenuation, some 67% attenuation, the same as various dry strains. Some will go to town in 48 hours, some in 14 days. It isn't whether it's from a dry package or a liquid package- it's the yeast health, temperature, correct pitching rates, etc.
To say that one finished faster or further isn't entirely accurate. If you're using liquid yeast without a starter, though, you're more than likely way underpitching, so it'll definitely take alot longer. That can be corrected (and make better beer) with the correct amount of yeast. Liquid or dry, the correct amount of yeast should be pitched.
To the OP, without a hydrometer reading, we can all guess as to whether it's done or not. It probably is. It might not be. No way to tell.
