Is it reasonable to use BRK as a lifelong savings vehicle?

Question

As someone that subscribes to the philosophy of value investing and wants a tax-efficient, set-it-and-forget-it long term savings vehicle, would it be reasonable to use Berkshire Hathaway B for that purpose?

Buffett is 91 and has underperformed the S&P 500 for the last decade. How confident are you in his future performance and that of his successors?
Berkshire is not a registered investment company like an ETF or mutual fund, so it pays taxes at the corporate level, including on the sale of appreciated shares of stock. A value ETF will periodically refresh its holdings and shareholders avoid paying taxes due to in-kind redemptions.

I would put more money in ETFs such as VTI and VXUS than in BRK, but I think BRK is a reasonable place to put some money.
