Several months ago, I was trying to decide between the Ascent and the Endura and I chose to go with the 3.5" Ascent 830, simply because it felt better in my hand. The Endura has a handle that is better-suited for a wide vaiety of grips if that is important to you, but the Endura "bites" my hand a bit more when I grip it tightly. This is just me, and since your hands are not the same as mine, you might not have a problem with it. Since then however, I have purchased the Endura and I really like it a lot. For Daily carry, I still prefer the Ascent, simply because I am used to the tip-down carry. As David Rock said, the Endura and Delica can be used in right or left hand fashion, but only tip-up, whereas the Ascent can be changed for tip-up or tip-down carry but can only be used in right-hand fashion. One more thing that I like about the Ascent is that it rides considerably lower in my pocket than the Endura or Delica. However, the Ascent is also wider at the pivot than the Spydies are at the butt, which in some of my pants, makes it tight to reach into my pocket for things like keys or chapstick, when I don't want the knife to get in the way. If you don't like the wideness of the pivot in the Ascent you can switch the clip to the butt-end of the knife which is very narrow, giving you a bit more room for your hand to grab things in your pocket. I haven't bothered to change the clip to the narrower butt-end, which indicates that it isn't that big of a problem for me.
Regarding the play in the blade, as far as I can tell, my Ascent has no vertical wobble (maybe I got lucky) and had a small amount of lateral play which I easily fixed by tightening the pivot pin. It has no wobble now whatsoever!
I have carried my Ascent daily since I bought it in August and have no complaints whatsoever, except that the hand is pretty much forced to hold the knife in only one position. The grip on both my Ascent and Endura is very secure, I just don't like the "bite" on the Endura when I grip it tightly. I suggest you try holding the Endura (and Delica if you're interested) and the Ascent in different hand positions, varying the tightness of the grip to see how you like them. Clip them in your pockets and see how they ride. I think it will just come down to which one YOU prefer! I don't think you can go wrong either way!
