I've been to see a couple acts - some that played at the Target Center and some that played at the Xcel Enery Center and I'd much prefer the latter over the former.
At the Target Center there are more bad seats and the acoustics are worse. Also, I had some VIP access at each concerts and I can tell you it is much harder to get specifics out of the Target Center staff than the Xcel staff.
But in the end, you don't have a choice where your favorite band plays, do you? So go to the Target Center to see them - just get good seats 'cause the bad ones can be bad and that just sucks.
