I love pumpkin/squash seeds and I've tried all the hull-less types - hoping to find one as tasty as the hulled seeds I get (as a by-product from the normal pumpkins and squash I grow for the flesh). None of the hull-less ones come out anywhere near the excellent snacking flavour of shelled 'normal' pumpkin' seeds.
OTOH. Hull-less are worth buying for using in recipes - in bread making, brioche & cakes (a few whole, mostly as flour via the coffee grinder - where they can provide the oil for the bake as well as flavour) - the 'flour' can also be used with mayo to make a convincing (and cheap) guacamole when avacados aren't available.
My snacking strategy is to choose your next year's pumpkins/squash by the size of the seeds - (the same mouthful for half the shelling) - that means medium to large fruits. eg. it's obvious that marrows' & butternuts' seeds are too small (though it is possible to crush VERY fresh seeds with a rolling pin, pick out the husks and eat the delicious mush - even easier with melon seed).
The best variety I ever found for seed size and flavour was a huge blue one called "Cerrano" from Ecuador - sadly there's been no UK source for at least 20 years and my own seed-keeping failed to keep them true, and then they started producing seeds with no germination at all. Galeux d'Eysines have probably the best seeds and flesh but you need a very hot summer to reach their best (for flesh).
There was a time when I would grow normal pumpkins/squash then eat the seeds and give (or even throw) the pumpkin away - but I now use the flesh grated into coleslaw and kimchi. Kimchi is a Korean pickle and it's especially useful as it's the only way I can use a whole medium pumpkin or squash before it goes mouldy (provided I have enough pots - fortunately pickles can survive being opened many times - this means I can use & re-use the 4L & 6L plastic jars sold for olives - and easily eat the kimchi long before they are anywhere near going off).
Just recently I've found I can now enjoy cooked pumpkin by mashing it with orange sweet potato (even better with nutmeg). Bizarrely, the combination of two foods blander than carrots can combine to make a mix that's as good if not better than carrots.
If (like my wife) you like pumpkin flesh you won't notice the difference, but if you find pumpkin bland, and orange sweet potato not much better - then you will be amazed by the combination. Try it.
Cheers.
PS. the flesh of all the hull-less types is really horribly bland - IMHO only fit for the compost heap, (I doubt if even pigs would eat it).
