It is an interesting thing to think about for awhile,
but in the end, keep in mind that those are just tools,
and the important thing are the underlying concepts and
the practice. Tools are just something that keep
evolving and it is normal (and maybe desirable) that we
find better ones and keep switching.
As I do more and more consulting, I keep seeing that
most teams need a better understanding and practice of
how and what to test than better tools. I guess you
surely found the same also...
