i like both, the pros of regular rope is that you can wind it easily on a line winder and so its very protable, i find the vinyl ones to float maybe better then rope but have the disadvantage of portability..mine is 18m so i have a pretty big ugly linewinder for it..
probably vinyl will be more durable too as it wont get weaker as easily as rope when you snag it on the rocks, or by fish gills (in case you use a speed stringer)
