I know Snow Leopard had some issues earlier in its run, but I assume patching has worked its way through that moreso.

Since I have a PC now, my Mac has 100% no longer been doing my gaming 'stuff', so that's not a real concern.

I've only worked with it at work, but it seems fine to me?

I upgraded, and I haven't really found anything wrong

I'd say go for it, just to have the latest update/security stuff/app store
