Both boards are fine. I regularly ride a 110L ASC F-One board at the wing school I teach at and its a fine board. Little big in my opinion and no straps is a miss, but fine for progression so definately a step up. The appletree is probably fine too, a little shorter so probably less glide, I always found the F-One board very easy to get up. Regarding the appletree, construction is a +, probably lighter than the F-One, although not necessarily more ding resistant. I own an Appletree Jazz, and while I like the construction and stiff feel, I dont really like the shape. Slow to plane, and the angle of attack feels all wrong without adjusting the foil rake (which brings other negative effects like additional slower planing). In my opinion there should be an incline between the deck and bottom angle (slightly raised frontfoot), and the Appletree designer doesnt share that opinion and goes for 100% parallel deck and bottom. You have to like that feel, I do not. Also depends on what foils you ride, F-One generally pairs well with everything.
Agree that the skin on the Appletrees isn't really ding resistant, but if you do get dings you don't have to worry about them absorbing water like you do on the F-One. Any 4 or 5 year old board has probably gotten a ding somewhere, so this would give me some peace of mind. The tracks on the Appletree are bombproof though, so it really shouldn't have any softening there like you might see on older boards from other manufacturers. Jazz is a pretty sluggish shape in general. I haven't ever had any issues with deck angle on the Appletrees personally, but F-One foils are made to be ridden with the rake on F-One boards, so thats probably what you are feeling.
