To be honest OP, I haven’t about both the bookmakers. So I would suggest you to avoid both the sites completely if you love your hard earned money. For the sake of design if you fall in the trap of these sites, then no one can save you from it and you will end up in making losses. What’s the problem with other reputable site’s design and UI? They have great user friendly design and mostly they are “trusted “. I would suggest you to play there and remove this design hype from your mind. Wishing you best of luck for your gambling career.
