I have two different very NHS experiences to report.
I've been waiting over two years to see a consultant about my extremly painful back & legs .I had an very short telephone consultation with him in Sept 2020, other than which I've had nothing but a quarterly email 'tick the boxes' survey, and a letter asking if I'd gone private yet - while my back gets worse and worse, and the only treatment on offer is ever-stronger painkillers .
OTOH, In March 2021 I went to see my doctor about an odd gurgling noise when I lay down to sleep. In very short order he sent me to a heart specialist who diagnosed my condition, got me into hospital within 2 days and temporarily (with medication) rectified the issue. The aftercare I received was excellent, and after six months I had a follow-up operation which will, hopefully, have cured the problem for good.
Both cases were from the same group of doctors, hospitals and ancillary services. This tells me that the problem isn't within the NHS, who are having to prioritise keeping people alive. The problem is that the government-provided funding for the NHS isn't enough. Ever since Cameron and Osbourne got elected in 2010 the budgets for NHS, Social Security etc. have been reduced in the name of 'balancing the books'. The Tories have long wanted to get rid of the NHS and set-up an insurance based system like the USA, under-funding the NHS is an obvious step towards this ambition.
TLDR The problem isn't the NHS, which prioritises what it can, the problem is a governing party who wants their donors to benefit from health privatisation.
TLDR 2 This was written 3/4 way down an excellent bottle of wine ('La Vieille Ferme' if you can find it), so it may not be as comprehensible as it should.
