About 8 kg to lose, eating in a moderate deficit, and I'm ravenous in the evenings which is where my week reliably falls apart. I've been using a cheap concentrate. People keep telling me isolate is better for cutting and I can't work out whether that's a real mechanism or just a price tier with better packaging. Budget is tight enough that a 30% price difference is a genuine consideration for me.
For fat loss, total protein and total calories are doing essentially all of the work. Isolate is more filtered — marginally more protein per gram, less lactose, less fat — which matters if you're lactose-sensitive or you're accounting for every gram at the end of a hard cut. At 8 kg to lose on a moderate deficit, concentrate is fine and the 30% belongs in your food budget.
That's what I suspected and nobody would just say it plainly.
Casein or a blend is worth trying for the evening slot specifically — it's thicker and sits heavier, which is exactly the point when the problem is feeling empty at 9pm. Costs about the same as isolate where I am, so it's not necessarily a step up in price.
Cheapest lever nobody mentions: buy unflavoured and mix it into things. Flavoured powder costs more, and for some people the sweetness makes them hungrier, which is precisely your failure mode.
Slight pushback — for me isolate genuinely was easier on the stomach, and 'the cheap one gives me wind so I stop taking it' is a completely legitimate reason to pay more. Buy a single-serve sachet of each before committing to 2 kg of anything.
Whatever you buy, weigh the scoop once on a kitchen scale. Mine was 8 g heavier than the stated serving, which is about 10% off the tub's claimed number of servings.

Your actual problem is evening hunger, not powder type. What fixed mine was moving protein and fibre later in the day instead of front-loading everything at breakfast. A shake at 9pm did more for my adherence than any change of product ever did.

Same, and I also stopped drinking calories at lunch when I could chew them instead. Chewing is doing something the shaker bottle isn't.
