Well those are not their unique selling points. Once you are a customer they tend not always reply to e-mails. They advertise that their service is top notch but with that i disagree.
The data feed is very accurate, however the platform has some bugs and crashes sometimes. ( few times a month )
Their edge are the cost and the fills you get. Also you can customize about anything which is a plus. Very fast indeed, but unfortunately it's not the total package. I've been with IB myself so I can compare. If you're trading-style is more like a scalper where you scale in and out then Lightspeed can be a better choice regardless of some of their negative scores. They have a demo available to see the platform, if you haven't tried it yet i would recommend it.
Good luck
