I have an Anvil foundry 10.5. The Anvil is 3 gallons bigger, so you can no sparge. Cleaning is pretty easy, and it uses 3x low density elements. The ability to switch between 120V and 240V is nice. Mash>boil time is about 45 minutes on 120 and about 20ish minutes on 240. The delay feature is great for preheating your water for your brew day. The malt pipe is a bit harder to clean then my old BIAB bag, and the chiller is just OK.
The price is great. I've never felt the need to adjust the temperature on my phone, so it didn't make sense to me to shell out an extra $700 for the grainfather. I don't do complicated step mashes, so manually setting the temperature isn't a big deal. I don't have any experience with the Grainfather, but I'm sure it has a nicer feel to it. I think the quality of the Anvil is good, but it's a "value" product by design.
Have you looked at the comparison chart on the Anvil website? It's pretty nice summary.
