Yes, lots of synths will get you something useful, and a lot will depend on your idea of what a 'good' pad sounds like. My personal favourites are:
Roland MKS-70 (essentially JX-8P/JX-10 too). The ultimate 'warm' pad for me, like a thick fur coat. Oberheim Xpander
. I almost I always use this through a Roland Dimension D for widening. Nice if I want a bit more 'edge' in the pad.
. Adds movement and twinkly/breathy high-frequency interest, but rarely do I use this alone.
Roland JP-8080. Can get close to the JX-type pad and also does a decent Jupiter emulation.
In the right context I also like a Super Jupiter for pads, but I'm usually looking for a 'harder' sound here and will frequently track two parts to add width.
Cubase's Embracer VSTi is very good and often makes it to a final mix too.
But layering is where it's at for me and any/all of the above are candidates.
