I'm building a touring bike and looking at drivetrain options

My first thoughts were a Stronglight Impact Triple, They look good value and appear to have excellent size options. but I have heard bad reviews about weaknesses.

Deore or Alivio were my second choice, both are proven touring drivetrains but are Deore worth the extra cash?

Also I have an 8 speed cassette at present, would switching to 9 speed be straightforward?

Any answers would be helpful
