I have P4, PPP, P5, VUE, Bryce, World Builder and some others, but If I had to have just ONE of them it would be Poser 5 WITHOUT QUESTION. Firefly is great once you tweak the default settings PLUS you have the PPP renderer in P5, and Firefly is better than VUE renderer hands down (again, after you learn to set it up properly). VUE has great atmospheres and is a bit more Poser-friendly than Bryce, but Bryce has great lighting and makes the best scenics. In the long run, each has it's own merits, and you will probably end up with them all, but for now, Poser 5 is the best thing to start with (unless you really need export to lightwave or maya - and if you have them why mess with Poser anyway ---- just kidding :-)) I still use PPP even though I have P5, but because of the low price on P5 I would buy it over PPP and wait for the P5 ProPack or 3rd party plugins if you need those export functions.
