I'm still really new, but I did just get the PEGASUS 12 Basic with the Titan Extruder and an E3d-V6 hot end, I finished assembling it early this month. Been printing for a few weeks, once I got everything square and calibrated it works great. I can't comment on which extruder is better or worse, for me at the beginning of my journey I'm just happy to be productive with it, once I get more experience I'll decide if I need to change the extruder. I'm hoping to move up to more flexible filaments so can support my Otter Box Phone case with a custom "rubberized" exterior (actually I think its more in the silicone family). Right now I'm just drawing up parts to repair damaged items or supplementing my bathroom "crap" holders.
