yes i have seen them all,
But circle, motifz and panache don't make copies, i personally own circle's clothes and they are beautiful too.
As for quality i find thread and motifz have the best quality of fabric, embroidery and designs among all of them including bareeze, Plus the machinery embroidery is so very IN now, and trust me its so much easier, i was a sucker for getting embroideries but when you get these gorgeous designs and all you have to do is get them stitched, it makes life a lot easier
Plus thread and motifs is the MOST popular in pakistan right now in what they do, so ofcourse they charge for their name and fame so do Karma, Hsy etc.
as for choice and preference, to each their own
