Polar is the bigger name, they can afford to put higher prices on their stuff because many will think it is better quality ( it may or may not be). Polar is certainly a high quality product. Other companies might be just as good or maybe better.
I know more people who have used Polar, so I know Polar has a good record. I know only one person with a Bios brand and so far he has no complaints with it. So for what little I know about it, Bios may be just as good as polar.
You can also get a HRM in a Timex watch, Timex is a proven brand so it is likely that their HRM are good too.
Try doing a google search for HRM reviews. It may give you the information you need to make a choice and feel confident with it.
