braided are more expensive but better - less prone to bulge and expand, goodridge make them i think there about £100 for front and back

rubbers are cheaper and probably average quality unless you buy bmw oem or a good brand

Do you need lines or hoses? Braided or rubber are the choice for hoses, copper (cunifer) or steel are the options for lines.

If this is about rust, then it's the lines you need. You can buy steel lengths from BMW and bend them yourself, but for a little more money you can buy a length of cunifer, some pipe unions and a flaring tool, and do it yourself. Plenty of advice on here if you use the search function, including links to the relevant tool on eBay.

Again, you can't use rubber for lines. Rubber is for hoses, not lines. Copper or steel for lines.
