I don't think you'll find any replicas that can do everything as well as the real deal. Some will be better in certain respects than others, but they will all fall short of the real thing, regardless of their price. But their weakness is they're all RDS sights pretending to be holosights.
So far, the only EOTech replica that I've seen or heard of that has a reticule bright enough for daytime use is the HurricanE series. I have both a Huang / G&P 552, and a HurricanE 552. You can read the comparative review I posted here:

If you want all those features, then there's only one way to get them - to buy a real EOTech. The other option, as stated by bruce, is to find a Bushness holosight, which is actually a civilian EOTech 551. It's cheaper than the EOTech brand, although they're made for Bushnell by EOTech. Short of that, you're stuck paying the big bucks if you want all those features.
