My humble and short opinion : what is better is Eiffel is its require/
ensure/invariant clauses, and what is better in Ada is its life world
capabilities. I use to use Eiffel for some attempt, but finally think
that the "every thing is class" of Eiffel turns into confusion and
that Eiffel was lacking for precise type specifications (in a few
words... deeply, I may tell more).

Although I love some Eiffel stuff, in the end, it is not so much
usable in real life as Ada is. Eiffel is a nice theroy experiment.

About Ada : think about Spark and Mika as well, beside of formal
clauses in Eiffel.
