Please help me make up my mind.

I currently have a Da Vinci 1.0. It was my 1^st 3d printer and I love it. I want to go the next step and get a printer that is a lot more flexible in terms of filament. I also want to be able to use Simplify 3d.
I think I have narrowed it down to the following

ROBO 3D R1
FlashForge Creator Pro
Leapfrog Creatr
LulzBot's TAZ 4

Would like some thoughts on this.
As a side note I am single so there is no one to piss off when buying this. :)

Thanks.

I Using a few Printers from GRR (NEO, Protos V1,X400 and a own Version of Protos V2) most filaments i tried worked ( for flexible I working on an Extruder to do this also)

about this one I can tell you a lot the one you ask for I can not help
