What make track would you choose, and why?

I agree with others. Choose a well known maker, with parts available
almost anywhere. Swish or, second choice, Harrison. Living in a house
with mixed curtain rails is as bad as mixed plastic plumbing or gutters.

Not that it stops me from having a large, old toolbox stuffed to the
gunnels with countless curtain hooks and accessories, all safely kept
'just in case' :-)
