Hey Joiner,
I just decided I do want the of1400 - that is, owning no other router, and wanting the option of a 12mm routerbit. The 1400 is noticeably heavier, but due to a perfect balance it does absolutely not feel cumbersome. I noticed that using it to do some on-workpiece-stuff feels more precise than with the 1010, maybe only because the base is larger and easier to balance.
To me the 1400 is the best compromise while wanting Festo and being unable to afford more than one. But:
The 1010 on the other hand is way better suited for the lr system and the VS600 system (Dovetail stuff and such). It's lighter, closer to the rail / lower center of gravity, which simply makes it faster to use and maybe even more accurate.
Having intensively used a 1010, I can say it's a fine tool and easy to handle, precise - everything you want.
I wouldn't say either one is better - check what you want to do. I don't know the specs of your other routers - Is one of them in the same range of power? Buy the 1010. All of them are smaller routers? Buy the 1400, and upgrade your router arsenal's power.
By the way, you could always sell the non green-and-black

buy a 1400 and live happily ever after...
