Which one should I choose for trading CFDs, is XM ok?

I have IBKR for regular investing, although that's not been going great since october last year... All US indexes barely moving, and QQQ even down lol.

Very bored, and to keep up with the markets, to even see any reason to read the headlines, starting to nibble on the trading side again. So far I'm on demo with XM, decent UI in the web, not hating it. They gave decent incentives to join, and they have special programs for gold and BTC, which is what I'm trading anyway. No swaps, so waiting a few days for the price to move to my target isn't an issue.

Which other broker would you recommend me to check out on demo? I want no swaps, and preferrably some bonuses for joining for real + obviously safety and the likelihood for them hunting my stops being 0. Don't want to even have to worry about that.
