Which account is better to sign up with - brixly.uk or finaltek.com?

When you look at Dedicated servers, please look at everything as a total package, tech specifications need to be with your needs and requirements. Security, support team's response time and hosting plans, all play a huge part in choice.

May not be within the same price range as the brands you are quoting, maybe a difference of a few dollars, but definitely worth investing if you are looking for a full-fledged robust dedicated server
