Yes, the change in taxes was one of the big positive surprises in retirement.
You may want to look into doing Roth conversions of your tax-deferred balance. You can get an idea of the tax you would pay on conversions by taking a pro forma return without conversions and then just adding in various amount of conversions and see the incremental tax.
I'm paying about 10% on my (both federal and state) which is much better than the 30+% I avoided when I deferred that income but I suspect you will pay more because your taxable portfolio is larger.
If something cannot endure laughter.... it cannot endure.
