As for pegs, it depends on what you’re doing. If you’re car camping just use the biggest, gnarliest pegs you can find and pound them in with a 20lb sledge hammer if you need to. If you’re backpacking, unironically Coughlan’s are great for sandy soil. They’re slightly longer than most y-shaped pegs. But if you can’t get them all the way down, the extra length can cause leverage that could cause them to wiggle loose.
Dutchware has some interesting y-pegs with a hook and a sort of boat cleat built into them. Your guy line can be pulled tightly through the hook similar to a truckers hitch. It’s a little too fancy for me.
If you don’t have pegs, or it’s too rocky, you can always tie a stick to the end of your guy line then put a large rock onto it.
