I have a puncture free tube in my rear wheel, and a regular in the front wheel. The pinch free tubes are also called downhill tubes sometimes. They are extreemly heavy, and a bit pricier than the regular. Most people dont use them. I just keep one in the rear since it takes the beating. I've had very few flats in my front wheel! I usualy just buy whatever the cheapest regular is. Wal-Mart has cheap tubes, and at the bike shop I usually buy specialized tubes, but sometimes they will have a different brand cheaper.
The brands on tubes are just American corperate marketing.
Most of them are made in the same factories, by the same companies in asia!
If you do go to walmart, dont buy their flat free tubes and puncture proof tubes. Those are no good. Their cheap tubes are good, but I 've tried those slime tubes, and those expensive tubes they have. They are no good. If you need a heavey tube, get it at the bike shop!
