is a 50/50 split better than paying weekly dues when driving a taxi cab?

I've never driven a taxi cab before but have an understanding of how it works. To some independent drivers it means you can work your own hours. You pay the cab company anywhere from $250-$350 a week in dues (this includes insurance, car maintenance, dispatching, etc). You pay for your own gas. I heard of drivers doing a 12 hour shift making anywhere from $250-$350 a day, sometimes more if experienced and depending on area. So pretty much a day's worth of work can pay off your week's dues.

Now a different company is asking for 50/50 split. This means there are no weekly dues but you pay the company half of what you make for the day. This might favor both sides depending if it's a slow day. If I make $200 a day, I give the company $100. Just in case if it's a slow week then I won't have to pay dues. Some drivers make money some don't depending on skills and assertiveness. I just want to hear opinions regarding this matter. I'm trying to work as a taxi cab driver so I can have that flexibility of working on my CDL license. My current job delivering pizzas usually requires me to be there on time, etc. plus relying on tips just isn't doing it for me. Some people tip and some don't.
