I've had terrible problems with 1&1.
I wouldn't recommend THEM at all !!
you do get a lot for your money - and if it all works fine and you don't need to deal with them for any issues, then fair enough ...
But I'd rather pay good money to get decent support - and they are really, really BAD when you need them ...
the effort and time spent speaking to a nice, but stupid indian lady that could not even grasp my simple, and clearly spoken request ... grrr ...
avoid them like the plague.
