For me Demirsoys results are close to the mentioned top 3. He does not do stick and place, makes motorised extraction and doesn't go for very high density (over 50) but with 1.25 per Graft he's far cheaper than the others. The reasons may be that he doesn't do a lot advertisement, he has only one external representative and not to many administration around him. But as already mentioned this is my own opinion and its always individual taste...
