Personally I recommend animefan's premium kit, but I'd ask for epoxy gelcoat vs coldcast. It's a beautiful kit and will make a fine ESB or ROTJ. The FP one on eBay is either a copy of this one or the budget FP, and will not come close to the quality of Ryans kit. Steer clear.
The FPH2 has some features that are more accurate for an ESB lid, but it also has some features that are not accurate(side flare, overall dome shape) so it's about a wash. Biggest difference will be the squint and dent are more accurate on the FPH2. Mind you this is some nit picky ****, but the OCD can kick in at any moment. I have both kits and can tell you that Ryans attention to detail was on par for the quality I've seen from FP. Both make great stuff.
The animefan FP is MR based as said earlier, and is just a touch bigger than the FPH2.
