You mean waiting 8 seconds less for a 1GB download is not worth it?? Well I suppose it might be worth it in certain circumstances not suitable for discussion here ….
It also boils down to what price you actually get it at, to me 910Mb is a bit over kill even for us here, but I do like the 110Mb upload.
But looking at the Full Fibre 500 from BT (Get 500Mb for the price of 300Mb) is a win win if already on the 300Mb package.
So I might just phone and ask for they best price deal that they can do for both of those packages and go on from there.
Looking at BT's prices going from their 500Mb:73Mb package to their 910Mb:110Mb package there is only a £10 price difference.
You might also need to find out what actual speed that you get, you might go for the 910Mb option but only get 500Mb speeds, BT would still say its still above their "Stay Fast Guarantee of 455Mb", so you need to also take that into the decision when picking a package.
