TFC Hercules - Looking for a retrospective opinion

I'm pretty interested in getting the TFC Hercules set, but I'm having trouble justifying $500 for it. There's a few things I'm wondering about it, and I'd like to get this information from owners who have had some playtime with the set.
1) How long have you had the Hercules set?
2) Tying in with how long you've had the set, how much have you played around with it?
3) Throughout your time with the set, how are the joints on both the individual figures and the combined form holding up?
4) I understand that quite a few TF hobbyists think that MakeToy's Giant has better limb connection joints than the Hercules set. If you own both Hercules and Giant, how big are the differences and would it be a deal breaker?
5) Is the Hercules set more of a display piece rather than a play piece? I do enjoy transforming my figures. That's why I get them, after all
I'll also add that I'm quite surprised that the Giant sets on eBay are quite a bit more expensive now than Hercules at BBTS or TFSource, but then again my understanding that Giant is mostly OOP.
