I've loved spitfire. I've been using it recently. I've been working on music for video games. I like retro games so chiptune would be great, but I've been doing a blend of retro with some modern instruments in it. Just experimenting and having fun with it. 🙂

I also loved spitfire. For me it sounds great.
In case of chiptune there are free options if you make music on windows.

Some kontakt libraries also for chiptune:

And also plogue has really great VST's (paid)
An alternative with plogue VST sforzando (free) is download soundfonts for using it into the soundfont sampler. But take care of some copyright issues.
