Hopefully this is not duplicating another thread. I am new to this forum and found a bunch of useful information here so thought I would share the comparison table I compiled when looking for a bag. I would be happy to hear comments on these bags or others you think I should have included. There were several I left out purely for subjective reasons (too casual/smart, too soft/hard etc.).

(note much rounding for ease)

My 'heart' choice is the beautiful Tri-Star. The 'head' choice is the Eagle Creek Adventure Weekender. That looks good value, light, capacious and probably easily tough enough for my infrequent trips. The other EC stuff I own has been good. Plus it meets the Euro airlines size restrictions.

Being keen on the sustainability angle I was a little surprised that there were not more bags made from recycled materials. The MLC looks best for that but sadly its a little too unstructured for me. And props to the Rick Steves Classic Back Door bag which is partly recycled material for a great price.
