I tend to simply look at the income they are providing on the rare occasions that frustration drives me to consider wielding the knife. So from a random selection from the bottom of your list I see
PHP - unblemished rising income record
SMDS - COVID blip, income back on track
I bought holdings in these over the last couple of years, so this is unsurprising as I wouldn't have done so had they shown a dodgier divi record.
WPP - don't hold, cut divi in 2019, not recovered to previous level but rising.
These I hold...
BLND - divi cuts 20/21, not recovered to previous levels, was hammered by COVID and now by interest rates. "We live on an Island and they're not making more land though".
TSCO - no divi as recently as 2017 and not setting the world alight since then either
SBRY - cut in 2017, slow rise in income since then.
Both victims of the great British supermarket wars of the last decade. But people still have to buy food, right?
LLOY - long term basket case saved only by the yield making it hard to replace the income if I sell it.
Aviva - income record like the edge of a saw blade for the last 20 years. Again, saved by its persistently high yield.
VOD - wtf? Another current high yielder.
And of course there is PSN. Let's go with "cyclical"?
Of that last tranche I've only bought SBRY and BLAND in the last decade or so, the latter a small top up as recently as this year because the divi looked sustainable or something
. SBRY doing fine capital wise, PSN breaking even and I bought it with no illusions about the UK housing market so I'd be inclined to keep all 3.
Everything else in that group down by lots. However, they are all paying a divi and since they've been largely ignored for so long their relative contribution to portfolio income shrinks every year, so although I wouldn't miss them if I could find a viable place for the cash to go if I sold them, I don't feel a pressing need to do anything at the moment. Any big divi cuts, or if I was tidying up my portfolio with an eye on imminent retirement might finally see them go though.
