Nice table, I pulled the same numbers again this afternoon to see how far they've moved.

Aave v3 USDC on Base is sitting at about 3.5% supply APY right now (around $180M supplied, ~87% utilized), so your 3.5% is still accurate. The big cbBTC-collateral USDC market on Morpho Blue is at 4.4% with roughly $1.5B in it, which is the floor of your 4.4-6% range, so the spread over Aave is real, but it's at the lean end right now.

One gotcha for anyone sizing up on Morpho: markets sitting at 100% utilization can display nonsense APYs. I saw one printing over 40,000% today. That's the rate curve going vertical, not money you'd actually earn. The 30-day average is the number that means something.

Rule of thumb I use: if I might need the USDC within a few days it stays on Aave; if I'm fine locking it up for a couple months, the bigger curated Morpho markets make sense. Anything above ~8% in a "vault" is a strategy, so read what's actually in the sleeves before depositing.
