-For (AD) U can switch 1-2 Quints for Attack spd
Example:Better Clear in Jungle,Better Farm also more attack
spd helps for pushing/farm under turret and u can proc more passive effects like yi double attack and vayne w
-For (AP) U always take HP.LVL in yellow since u already a apc which means u will deal mostly dmg in mid/late and the enemy will know this and try to take u out so its more likely to take hp/lvl over armor/hp
But that changes for 2 arts of champs
-If ur enemy is a AD champ(Zed,Talon,etc) its always good to take some armor since they can snowball pretty hard if u cant deal with them early on
-If ur vs a assassin apc(Syndra,LB,Ahri) There u take HP/HP.LVL and in blues u go to MR otherwise u can switch to MR.LVL if u know ur matchup and u need that in mid/lategame

Both of these pages are as generic as you can get, but most people will run different things, depending on preference/match ups.
