Best I got was Lidi's own, but looking good and lighting room are not the same, the Lidi strip had a high lumin output, zigbee controlled but if not needed they your paying for something you don't want.
Most of that flat strip stuff i believe becomes problematic over 5 metres, over that i have seen the joints overheat, so you may need to break it down to numerous drivers drivers.
Led rope i think may be better for longer lengths, maybe opt for 24volt gear
