You'll probably want to stay away from the GBP stock since it's probably taxable (UK stamp duty) through IB.
Whether to trade the EUR or USD stock would probably depend on which hours you want to trade. Are you based in Europe or US-based? Do you have charts for either one? Do you care?
If you are a US resident, it's probably better to stay with USD stocks. They're traded on US exchanges during US daytime hours and charting/data is generally available & very cheap/free.
Data/charting for non-US stocks costs more, is difficult to get & commississions are generally higher as well on foreign-listed securities.
It all matters in order to reach a proper decision.
BTW, some stocks are truly "multinational" in their trading. Some stocks trade heavily in different parts of the world. Australia's BHP for example trades in London, NYSE, AU, So. Africa and maybe some other exchanges.
Some other "International" stocks may be listed in 3-4 different world exchanges but trade primarily in 1 exchange and sometimes 100-200 shares in the other exchanges. So, try to always go where a stock's primary market is.
