Okay decided I'm going to splash out on something nice as I'm spunking enough on the wheels. So probably some Vittoria Evo CX or the new graphene variant.

Do tubulars tend to differ in profile to same degree as clinchers? Or does 25mm tend to be a true 25mm?

Asking as I'm fairly tight for clearance. Rims are 24.3mm on the wheels I've bought so assuming that means I can't run a 23mm tub?

Anybody know how the Vittorias measure up specifically?

Tubulars tend, on the whole, to be pretty true to width. Depending upon construction their height, however, can differ a bit. Recall the shape of the tyre, in contrast to clinchers, is immutable to rim design. Tubular tyres are round. Given variation in roundness, etc. I'd avoid overly tight fits. Most frames, however, will accommodate 25mm tubulars. Some bicycles might have problems fitting Clement Campionato del Mondo (28mm) but they've been out of production for more than 30 years..

Tubs tend to follow clinchers in my experience. Veloflex and Vittoria tend to come up smaller than Continental.

Re your tub choice, what do you want them for ? If mostly city riding and/or wet weather riding I'd stick with Conti as they tend to be more durable and grippier. Regular Sprinters are durable enough, no need for Gatorskins. Competitions if you're feeling a bit more spendy.

If you want something more traditionally tub like with a latex tube, then Veloflex. They're more fragile than Conti's, but seem to have better grip and durability compared to Vittoria.

I tried city riding on Vittoria Corsa EVO CX IIIs once and found they lasted about a month, normally cut to death by glass.
