I've been using the Poser-Vue workflow since 2007, initially started with Esprit but found it too limiting so upgraded to Infinite and never regretted it.

The initial outlay for Infinite is pretty high but the maintenance plan takes the sting out of it, this year I paid just £160 to renew - for that I get the .5 and full version releases.

Vue is actually pretty good for interior scenes too once you get the hang of the lighting and atmosphere controls

eg

 

The new Daylight Portals in 2014.5 improve things even further allowing you to control exactly where light enters a structure.
