Speed from Different EC2 Regions

Question

I'm based in the UK, as are all users of my web app, and currently host in the EU-West region. The US-East region is quite a bit cheaper and I'm using a service from another company that locate their servers in the US-East region (meaning that I'll have data transfer costs between regions if I kept things in the EU). Has much of a speed difference am I likely to see between the two?
