This is something I've thought about a great deal and in the end it varies so much with individual circumstances.
We have a very high (85%) of retirement funds in tax-deferred accounts. So high taxes on RMDs are a big consideration. Especially if DH leaves me a widow, which is likely. Right now I'm mostly pulling from IRAs for living expenses (I have a small pension and DH has a low SSDI income) and doing modest Roth conversions. The benefits of waiting for me to claim SS (I was the much higher earning spouse) seem worth it.
1. Lower taxes on lower RMDs
2. Lower taxes due to 15% untaxed higher SS benefit
3. Higher survivor benefit for my DH if I should pass first
It sounds like your tax deferred accounts are a much lower %, which would change the picture significantly.
