huge inventory right on the spot for you to choose. i used to be a big fan of Golfsmith, i am still a GS fan but PGASuperStore in Chandler is better than Golfsmith Chandler.
For great deals you still have to do your homework, but for walk in and purchase PGA is better for me. The golf simulator is handful and the bays are always available instantly (i usually visit the store around 6:00p). Customer service is good but don't expect instant pestering from the staff. You need to know what you want, shop yourself or get instant help... by asking. You keep you mouth shut they keep theirs.
for club making tools its still Maltby and GS online to do the tricks. For apparel and golf clubs and accessories PGA has huge selections. Club fitting PGA has more bays, for club reshaft, regrip you have Dave, he is the dedicated person. GS? none; you have to get a hold of a sale staff.
