I believe the answer to your question boils down to a discussion of tax strategies and personal situation, both now and in the future. As a result, it's pretty hard to give a concrete example to the question as asked right now.
For example, if your tax rate now is likely to be higher than your tax rate at retirement (it is for most people), than putting the higher growth ETF in a retirement fund makes some sense. But even then, there are other considerations. However, if the opposite is true (which could happen if your income is growing so fast that your retirement income looks like it will be higher than your current income), than you might want the flexibility of holding all your ETFs in your non-tax advantaged brokerage account so that IF you do incur capital gains they are paid at prevailing, presumably lower tax rates. (I assume you meant a brokerage account rather than a savings account since you usually can't hold ETFs in a savings account.)
I also want to mention that a holding in a corp account isn't necessarily taxed twice. It depends on the corporation type and the type of distribution. For example, S corps pay no federal income tax themselves. Instead the owners pay taxes when money is distributed to them as personal income. Which means you could trickle out the earnings from an holdings there such that it keeps you under any given federal tax bracket (assuming it's your only personal income.) This might come in handy when retired for example. Also, distribution of the holdings as dividends would incur cap gains tax rates rather than personal income tax rates.
One thing I would definitely say: any holdings in a Roth account (IRA, 401k) will have no future taxes on earnings or distributions (unless the gov't changes its mind.) Thus, putting your highest total return ETF there would always be the right move.
