Which Long-Term Bond ETF Is the Better Buy: iShares' IGLB or Its Treasury Rival TLT?

The article compares two long-term bond ETFs: IGLB (10+ Year Investment Grade Corporate Bond ETF) and TLT (20+ Year Treasury Bond ETF). IGLB offers lower costs (0.04% vs 0.15% expense ratio), higher yields (5.20% vs 4.60%), and better 5-year returns ($908 vs $714 on $1,000 invested), while TLT provides pure government debt exposure with lower credit risk but higher interest rate sensitivity. The choice depends on whether investors prefer corporate credit risk or interest rate risk.
