Does it make more sense to go with ERS + basic plan rather than FRS + standard plan? Which combination is a better plan financially assuming monthly payout amount is not that important.
More information required. What are your objectives?
One of the few clear facts is that the CPF LIFE Basic Plan is
never better for the CPF member him/herself. The Basic Plan always provides a lower monthly payout than the Standard Plan while the member is still alive. And it doesn't offer the 2%/year escalation feature that the Escalating Plan provides. The only thing the Basic Plan can do is maintain a higher residual for somewhat longer from (only) the CPF Retirement Account.
You have 3 basic "knobs" you can adjust with CPF LIFE:
1. The principal (input value). The principal can be the Basic Retirement Sum (with property pledge/charge), the Full Retirement Sum, the Enhanced Retirement Sum at age 55, the Enhanced Retirement Sum at age 55 plus top ups to every new Enhanced Retirement Sum thereafter, or something in between (example: FRS+25%). The higher and earlier the input principal, the higher the monthly payout amount and residuals (for any/every age when residuals apply).
2. Age when payouts start. That can be the month you turn age 65, the month you turn age 70, or any time in between. The longer you wait to start payouts the higher your monthly payout and the higher the residuals (for any/every age when residuals apply).
3. The payout plan. That can be the Standard Plan, the Escalating Plan, or the Basic Plan. The Standard Plan provides a higher monthly payout for life but a lower residual than the Basic Plan (for any age when there's a residual). The Escalating Plan is essentially the Standard Plan but with a 2%/year lifetime slope applied, the only payout plan that provides any defense against inflation.
That's it, really! Exactly how to set those knobs depends on what goals you're trying to achieve. FWIW in my household we'll be at the ERS at our respective 55th birthdays (both my spouse and I), we expect to top up to the new ERSes each time the ERS is raised, we'll defer payout start to age 70 (the default actually), and we'll most likely choose the Escalating Plan when the time comes if we're in decent or better health at that time (age 69+). We're doing well financially, so the best option for us is to maximize the asset protection, longevity insurance, and inflation defense aspects of CPF LIFE. So that's our plan, and we've already prepared well for these "knob" settings.
