Loftzone vs Loftleg XL with timber crossbeams

Need some advice on loft boarding. The DIY Loftzone option is £460, but I've got a quote from a reputable company for Loftleg XL with timber cross beams for £572. Is the Loftzone option worth the cost, or would I be better off paying a bit extra for the Loftleg and saving myself some time? Cheers!
