Which Long-Term Corporate Bond ETF Is the Better Buy: Vanguard’s VCLT or State Street’s SPLB?

Vanguard's VCLT and State Street's SPLB are nearly identical long-term corporate bond ETFs with virtually the same performance, fees, and risk profiles. VCLT has a slightly lower expense ratio (0.03% vs 0.04%), higher yield (6.0% vs 5.8%), and significantly larger assets under management ($8.3B vs $1.2B), making it the more dependable default choice for most long-term investors, though SPLB remains equally sound for State Street platform users.
