English to German Bus/Financial Marketing

Hi, everybody!

This is a marketing questionnaire. ("Area" is referring to areas in the technology sector.)

Question:
Which area has delivered the *most value* for the end consumer in the past five years?

Answer: a) operating systems b) search portals c) software applications d) servers etc.

Question 2:
And which area do you think will deliver the *best value* for the end consumer in the next five years?

Answer: a) operating systems b) search portals c) software applications d) servers etc.

Since these two questions are related, I think it would be best to use the same translation for "best value" and "most value". However - isn't there a difference between "best" and "most" value?

The wording "deliver the best value"/"has delivered the most value" makes the sentence even more confusing.

Any translation ideas? Thanks!!
