GP4's are lovely for 28mm and smaller. But I'm a big fan of Marathon Supreme for 32mm and larger (I run 35mm). They are incredibly supple, not quite as fast as GP4's, but much quicker than touring tyres. Fantastic grip on any combination of wet, dry, cold, warm. I've had no punctures on crap chiltern lanes and a fair chunk of byway and canal paths. I'm not particularly quick at Audax (under 11 hours if I'm lucky) - but compliant tyres mean I can still function as a human the next day with no aches or pains.

Expensive but I got a pair from wiggle last week.

Just physically tried what would fit in my Look 566 frame.

GP5000 28 is a close but workable fit.
GP4seasons 28 is a much bigger tyre: not so much width, it might have fitted widthy-ways, but it's much taller, and fouled the BB shell way before the wheel was anything like forward enough to reach the dropouts.

Pirelli Cinturato TLR. Can get it quite wide and the balance between rolling resistance and protection is pretty good. Certainly better than Marathon greens.

Anyone tried the Jack Brown tyres from Planet X? Made by Panaracer, and quite cheap anyway.

I have three of them on the trike . I think of them as a less costly pasela pt . Go on to the rim easily . Come off the rim when required with out a fight , & roll well . Better grip than the previous gatorskins  . I got the first batch for  £12.99 each so really good value . I did blow the side wall out on one , but I am fairly certain I hit a bit of barb wire . At least I could ride home on two wheels . Very hard to judge protection from visitation , but carcass looks the same as aforementioned pt , which I find is good till the tread gets thin .

The Conti Ultra Sport III roll well (on a par with Grand Prix) and dirt cheap

I can't find the standard GP5000 in 32mm but I can get the GP5000S TR in 32mm. The former is max pressure 102psi and ply/tpi 3/330. The latter 73psi & 2/220.

How much difference is that all likely to make? Wrt rolling well and puncture resistance? And, given that I'm looking at >£150 for a pair am I better off going for something like the GP 4 seasons (or something else entirely)?

For reference I'm on a Trek Crossrip (a vaguely cyclocross road bike, disc brakes, full mudguards [sks longboards I think]), I weigh about 70kg, and am aiming for LEL.

Been on the current GP5000 for a good while (they might have enough life left but I don't want to get to a few days out and have to scramble for a replacement) and they seem good but I was previously commuting on marathon pluses so anything will roll well after that.

As it happens, I fitted a pair of 32mm GP5000 TR yesterday.  I'm also the same weight as you.  However I am using them tubeless.  A tyre pressure website told me I should have them at 53psi, based on weight and rim width, which is what I will go with.  If I was using tubes I'd want a bit more air but 70 would feel like enough. 

Whether they will be faster at 53 vs 70psi vs 100 depends on the surface.  If it's completely smooth then 100psi faster.  For typical UK road I suspect the reverse. 
 
With tubes / without sealant, they are not going to be terribly puncture resistant at any pressure - they are racing tyres.

The gp5000 in 30mm is in stock in a few places if you can live with a 2mm difference. I think I bought the last 32mm in the galaxy last week - it arrived in a very battered box.

I’m going conti hard shell on the rear/gp5000 front.  I’ve been averaging a rear puncture every 500k on lightweight tyres (bontrager r3 and gp5000) the most recent of which was a half cm slash that’s cut the cords and I think killed the tyre - it went with a bang! In contrast I put 4,500k on a conti hard shell on my other bike with no punctures, and my son is on 2,500k on his with no punctures.

I know logically that the fast racing tyres should save enough time to justify the punctures, but since the fairy tends to visit when it’s dark and raining, I’ll sacrifice a few minutes of pace to avoid the discomfort and unpredictability.
