Over the trailing five-year window, VGT and XLK moved almost in lockstep (daily-return correlation 0.99), so holding both adds little diversification.
VGT delivered the higher five-year annualized total return (22.7% vs 21.8% for XLK), though it is only one window and says nothing about the future.
On cost, XLK is cheaper — 0.08% versus 0.09% for VGT.
