Accurate results?

So i know there are a number of websites that gives you your natal chat for free and gives you the option of competing it even if you don't know your birth time. The more well known one is astro.cafeastrology.com which I have found to be more accurate however there are other sites that gives me different results.

I want to know if you found particular websites to be more accurate than others and if so which ones? And for those that don't know their birth times how serious do you take your placements?

I'm not sure about which ones are most accurate... but I use alwaysastrology.com mainly because it is interactive so you can hover over whatever planet and it gives you your sign, aspects and houses right there with a description too.

It's just really easy to follow and understand, made it easier for me because I'm a noob. 😛
