The K30 holds back a lot less, 5g if I recall. The funny thing about the PEAK is that it will do a very good job of clearing it's grind path while running empty. If I grind until there are no longer beans in the burrs, I can still get 8-10g of ground coffee out by grinding "dry". The K30 doesn't do this. Most other grinders don't do this. Dittings do do this. So the PEAK's shot to shot grind path retention is higher than the K30's, but it's bean to bean retention is very low. Hopper to hopper retention is high for both (that's beans left in the grinder after closing the hopper gate and removing it).

Now, anyone is welcome to buy whatever they want, and I'm generally on board with going large on a grinder. However, I've been feeling that the increase in the number of high end grinders that equal or surpass the price of a Robur E has pushed this community's price expectations upward (and I would assume other online coffee enthusiast communities as well) without a solid growth in understanding of what these grinders are and aren't good at doing. It's hard enough to get people to grok the outcomes of The Titan Grinder Project and the "Can it beat a Robur" shoot out. Add to that grinders whose strengths lie in a very narrow stylistic range (light and long shots in the EK's case), grinders with commercial specific features (active heat mitigation, long life burr coatings), and grinders with commercial specific technical innovations (ClimaPro), and the entirely new grinders from boutique builders (Lyn Weber, Denis, and Frank); you have quite a bit new stuff and very few community members with actual first hand comparative experience. This leads to a lot of underinformed people mistaking price for a linear measure of quality or ability, which is not the case.

As a note: although you could buy both a PEAK and a K30 and return one after trying, you have a responsibility to let your vendor know that this is your intention. I think a lot of the vendors that participate/contribute to this community deserve at least that.
