Top two are my collector and user. Something about the Phoenix's design always appealed to me, and it fits the hand really well. If I could only keep one Spyderco, it would be this one.
The Para 3 lightweight (S90V in this case) is what I zeroed in on as a user. I know you said you want something with a longer blade, larger grip, and beefy build, but that's not exactly where Spyderco puts their best foot forward (I'd look at Cold Steel for that). Spyderco specializes in a different form of functionality. If you're using a knife regularly, it's really nice to have something lightweight and unobtrusive. The Para 3 LW is the best example of what Spyderco does well IMO. It's small in the pocket and weighs next to nothing, but performs exceptionally well for real tasks. The blade is a slicy flat grind but a little thicker than most Spydercos, so durable. The lock is fidgety and actually much stronger than you'd think due to the force distribution of the design. The main grip is a little small, but it's full-sized if you choke up and use the choil. Essentially it's a utilitarian way to get all the function you need while giving up as little as possible.
Since the Phoenix is long out of production, my recommendation for you would be to pick up the Swayback at the bottom. It's being heavily discounted right now since it's recently discontinued, and it's a pretty unique knife. It has possibly the thinnest BTE grind of any Spyderco, and that combined with the hollow grind and polished stonewash finish make it glide through material like nothing else. The contoured handles are also a nice touch, and it has an unique internal stop pin design that gives it a smooth action with no play. It's the closest action I've felt to a Chris Reeve Sebenza. It's not the easiest to quickly flick open, the stock clip isn't the best match, and the handle shape is intended more for reverse grip than conventional, but if you can get over that it's a great addition to the collection. I think once the supply dries up, the unique characteristics of this knife will make it highly collectible.
