Great overview mark. Well researched and presented
however as most of us know we often collect with our heart and not our brain
As you correctly say " there is no right answer"
Both have pluses and minuses
Being mainly a vintage collector I would tend to 5070 but I love the new 5170g
I stupidly passed up the 5070 when it was initially offered- still kicking myself and now looking for a reasonable 5070g
Love your work
