I have a youngish (5th leaf) Pixie Crunch tree that fruited the past two seasons, quite generously for a still small (5’) tree. I probably left too many apples on this season, ~70, so not only were most a bit smaller than last season’s, but I may have runted the tree. I keep mine at 8’, so it may not be that big an issue. Anyway, it’s a really good apple, true to its name texturally with an approachable, balanced flavor and with very little sunburn in a year where many of the heirloom apples I fruited sunburned mildly to badly (ah, Karmijn, what could have been between us thus fall/winter 
). It’s a keeper in my area.
Another apple I fruited for the first time this year that really excites me (liked it more than the very likable PC this year) is one I don’t read about on fruit forums at all. Sir Prize, a PRI selection named in 1975, has Golden Delicious in it’s heritage twice and resembles that variety, though it’s a big improvement in flavor, and I really like a properly ripened home-grown GD. It’s sprightly-sweet with tender, crisp fine-grained flesh. I had a small crop of about a dozen fruits on a couple of branches I grafted to an existing young tree in 2013.
The only negatives were some bird problems before I was able to net the tree and a little sunburn on the most exposed fruit. I’d love to stash a hundred for the winter, as it’s supposed to keep six months under refrigeration. It’s worth a trial for folks in hot, dry summer climates for sure. Those of you with CAR and fire blight problems might think a bit harder on adding it, as it’s moderately susceptible to the former and susceptible to the latter.
If your conditions are right, don’t miss out on trialing this apple.
