Tried all non chemical options and now there's hundreds, best to pull up and start again with something different or persevere?

I'd start again with something different. There was a thread a little while back with some good suggestions. I think one if them was lonicera.
In London. Keen but lazy.
Thank you, looked at lonicera, but growth rate is quite high. friend suggested ILEX CRENATA, but new to me, but I have decided to take the lot out and start fresh with something else, but would still like some other suggestions.
Oh - btm - you're only in the next county... If those descend on my plants I'm having the whole lot out. Have been battling blight ever since the damned stuff went in 5 years ago and caterpillars would be the final straw.
Apparently 2013 / 14 was a particularly bad year for box blight and I'm pretty sure the disease came in with the bare root plants I bought - all 300 or so of them. It was a massive task getting them in the ground at the end of a particularly cold spring and they've been a constant source of angst ever since.
Unfortunately, when they're looking good there is absolutely nothing as fine as a manicured hedge of buxus - but sometimes life is just too short. Lonicera is too fast growing to be a decent replacement. Several people recommend the ilex crennata and I'd also look at yew - apparently it can be kept very low - but I'm not too sure how successful it would be. There's also a dwarf berberis which might be worth checking out.
Didn't Beechgrove do a trial of alternatives to box? Not too sure how relevant their findings would be for us in the hot dry SE though.

Beechgrove had a couple of lonicera, one was "Tidy tips" the other was "Baggesen's Gold". I think the presenter preferred the "Tidy tips" one .
I think another was a cotoneaster, possibly simonsii ?
There's also Osmanthus burkwoodii.
There may be more ideas here
A lot depends on how quickly you need it to grow.
