Although avoid anything with ethanol if its an option - although its getting harder to find now that Gull isn't offering it any more. I think mostly it's now Mobil and some BP outfits offering 98 - I suspect that as less stations are stocking the 98 option the 96 won't be as much of an issue as most people are either 91 users or 98 so the poor middle grade gets a bit stale!
