Well i think the E3D might be better, Since its longer in development,

Prusa is like 1 year old and its still its second version.

I did hear good things about both so i would say throw the dice and just take one ^^ i guess E3D might be better as price goes but the Prusa might be shorter aka more build volume (E3D is pretty long 72mm if i am right)

Also you forgot a O, its Oostende ^^ Well i guess it may be still there ^^ You could always try and look it up on google maps :P
