"Well I think you will find that Fairfax outperformed Berkshire during that period despite a long stretch during that period that Fairfax describes as their "seven lean years" were they woefully underperformed for a number of reasons (loss-making equity hedging and poor equity investment selections being the main ones). Fairfax pays a dividend and it is important to include those in your comparison. But it is close enough to a tie that it doesn't matter.

Thanks for the info. I agree FFH is a good alternative for diversification. Over the years, I have found qualitative is more important than quantitative in investment. In this regard, I would stick with BRK since I have known it much better and have more confident. I think high tech would be a better alternative as it become more clear year by year that's the future. I have slowly tapped into high tech in the past two years, Meta, Google. I only regret that I didn't dive into it two years ago when the tide fell to the bottom.
