Which Long-Term Bond ETF Is the Better Buy: State Street's SPLB or Vanguard's VGLT?

State Street's SPLB and Vanguard's VGLT offer different approaches to long-term bond investing. SPLB provides higher yields (5.5%) through corporate bonds but carries credit risk, while VGLT offers safer Treasury bonds with a lower expense ratio (0.03%) but lower yields (4.7%). SPLB has shown better 5-year returns and lower drawdowns, making it suitable for income-focused investors, while VGLT serves as a defensive safe-haven option.
