I hope 3-4" away from the wall is an exaggeration.As far as looks, it is way better than the Toto Drakes I had installed in my previous home. They were too small in my opinion and looked like something you might install in a child's bathroom. The tank looked so dinky against the wall and set away from the wall about 3-4 inches. This basically negated any advantage you might think you get with a smaller footprint because the edge of the bowl was still about the same distance from the wall as a "normal" size toilet like the Champion 4. The Champion 4 has a nice, full size tank that fits right up next to the wall with a 12" rough-in.
Not sure which Drake you have round front has a 3/4" gap and elongated has a 1-1/8" gap.
Champion 4 has a 1" gap.
Maintenance would be on the top of my list, i would rather pay the extra to have a trouble free unit.Maintenance will be the determining factor and only time will tell on that. If I just have to replace a couple of seals every 2-3 years like i would have to replace the flapper on the Drake, I will be very happy with my purchase. Oh, and did I mention that the Champion 4 is about $100 cheaper than the Drake and has a 10 year warranty?
Moen has a lifetime guarantee on there cartridge, i used to change it every year or so, i replaced with a Grohe and 6 years later still works like day one and they also have a lifetime guarantee which means nothing if you never use it.
