Intuition adds to arguably the most universally-useful skill in the game (Perception), your initiative, and your Defense Test.
Characters with this modifcation receive a +1 dice pool modifer to all Intuition-linked skill tests.
Neither Initiative or Defense Tests are skill based, they are attribute based and as such not affected, while it costs as much essence as a level 2 Cerebellum Booster which gives a straight +2 Intuition.
And while Perception is one of the most usefull skills, apart from Disguise and Assensing there arent't alot of usefull skills in Intuition(and Assensing is at odds with spending essence) and Perception can very easily be improved via Vision/Audio Enhancement and even Cybereyes/Ears would give you more bang for a lot less Nuyen.
Meanwhile Logic is nearly exclusively used for for Skill tests(some Matrix and Magic Defense tests are not), and there are a lot of them. For a Decker it simply gives +1 to all his main skills and Riggers get +1 to several main and secondary skills(depending on how you play your Rigger of course).
Maybe the limitation for "skill tests" only, didn't exist in the beginning and it was never corrected, but with the current limitation, it's nearly useless for a lot of essence.
Or someone just switched the costs for Logic and Intuition, because 0.1 essence for +1 Logic(even if it is only skill test), is a bargain. Then again it does costs 63k, and Riggers and Deckers need all the Nuyen they can get.
