Comparison

ISF vs SWDA

iShares Core FTSE 100 UCITS ETF GBP (Dist) (ISF) and iShares Core MSCI World UCITS ETF (SWDA): what each one is, what it costs, how it has done before and after inflation, how far it fell, and how much of what they hold is the same. Nothing here says which one to choose.

Two to four funds. Each one you add changes the link, so a comparison can be shared.
