I've got a 3e 2078, and it's very nice. I use the 12 hour bio function so the fish can rest with low flow at night :yaw1:
Dunno if it's worth the extra as it's my first Eheim, but it's a great filter with a ton of media and a very strong, quiet pump.
The only negative is it's a bit fiddly to prime and get going. By comparison, my cheap-ish Aqua-El self primes like a champ, is also very quiet, but doesn't have anywhere near the throughput.
Mine keeps the water very clear.
