For me it comes down to trust in this regard and not to the technical advantage both of these implementations have. Less than a year ago, Gavin and Mike Hearn pitched up here and dropped XT on us.

They had ulterior motives then, and it was quickly picked up by the more technically incline people here... Mike threw a temper tantrum and left to go work for the competition and Gavin were left with a

empty bag. His only option was to distance himself from XT and to submit a new implementation that would get better support. So he quickly put 2 and 2 together and saw a lot of people were asking

for bigger block sizes. He then jumped in with a implementation to address that. {Because he knew a lot more people will support that} ... On the other hand... The Core developers had a full deck of

cards from the start, and came in with a whole set of solutions for a lot of our problems. { SegWit / Side chains ..... } I will go with the people with a long term vision.... not just a short term solution to

regain control over the development.. a so called power grab.
