Metal poles (steel/aluminium), I think, are generally held to be stronger and more stable than GRP. 'Top end' tents tend to have metal poles.
One advantage of metal is that the poles are often preformed into the finished shape meaning they are not stressed just by the act of erecting the tent.
As tents get bigger, the poles necessarily get thicker and heavier. By the time you get to a mid-sized family tent a steel (tubular) pole is likely to be lighter than the (solid) GRP equivalent.
As for pegs we use standard V-shaped steel pegs for the main guys. If the ground gets very wet then we may well double peg strategic guys.
We always place the steel pins at an angle rather than vertically. If it's particularly rocky/stoney we use rock pegs. It may take a couple of tries but I've never been defeated in getting a rock peg properly buried.
I imagine the screw pegs could be a useful addition to the armament but, for me, carrying a drill/charger/driver seems too much hassle to fix a non-existent problem.

Re:corkscrew type pegs. They sell longer and bigger ones for holding your dog in place. I presume that they can pull harder than the wind, depending on dog size. Inverted U/V pegs sometimes tend to pull out when the ground is soft, as in rain and wind conditions, no matter what angle you put them in. This is why I bought the Delta pegs, they just get pulled harder into the ground due to the roughly 70 degree angle between upper and lower parts of the peg. The peg is also wide like a T section if you were to look from the end, which means it resists cutting into the soil.
As far as poles are concerned, carbon fibre is light and as strong as steel on paper, but with the flexing due to the wind, people have seen these splinter and break. Otherwise why sell spares ?Aluminium is used in my mountain tent which is small and light and has stood up to gale force winds. However this does not mean size for size they would be ok on a larger tent.
Tensile strength is not really any measure I would care to use, given that poles are subject to shear stress more than tensile stress. I would imagine a tensometer test of the 2 materials would show aluminium as having the greatest elastic range, which would in itself indicate that they could bend further than carbon fibre.
I just wondered what experience my fellow campers have had with the different types ?

its all about angles with pegs though, if they are used with a guy rope you can get a them to go in at a fair old angle, if this angle is back towards the tent, and the guy is away even the strongest of wind will make very little difference, i just use standard plastic pegs mostly, i find they 'grip' the ground quite well, if the ground is firmer i have some chunky traditional pegs, as well as the rock type. im not convinced that fancy pegs make that much difference, expecially on a well pitched tent.
never had an issue in many a strong wind, providing guys are nice and taut at the correct angle.
Im also glad im not the only guy rope fiddler out there, i often take a wonder around to check and tighten where necessary, although i am guilty of not using all the guys if i am staying somewhere with more acceptable weather.
