IC Markets or Pepperstone UK

I’ve narrowed it down to these 2 brokers. IC Markets is a lot bigger and seem to be more reliable, but Pepperstone is FCA regulated which means that I can protect up to £50,000 of my capital. Another thing is that IC Markets has 100 ping, whereas Pepperstonen only has 40 - it might not be a big deal, but I thought I should mention it.

Can I get some suggestions please?
