The SE, like the E, has some extra electro-magical features that mostly seem to involve using the presser bar lifter in an extra upper position to activate the bobbin winder and bring up the bobbin thread instead of having to manually turn the wheel (also no stop motion wheel to disengage). As far as I can tell, the difference between the E and SE is that the SE has a big wedge foot control...
The 1222 SE is the most modern machine (and most expensive, still) in my house. I'm a little scared of it, but it does sew very slowly when you want it to.
