You need to check how much (maybe all) of the lump sums will be tax free. It depends how much you need the lump sum. I declined from taking the max possible tax free lump sum because it was more than I could imagine needing on the next year or so given existing savings and I'd have just worried about how to invest it. You are not supposed to recycle tax free cash through a pension (and get tax relief again) and there are some restrictions on how much you can put back in each year, but you could probably recycle it through a spouse's pension plan.
Schemes tend to set the terms so that the options are equivalent on average but it all depends on how long you live, your current savings, other income, your spending plans, your tax position, etc.
