I just got throught replaying the game for Xbox 360 and wanted to give my thoughts on Batman's gadgets and upgrades for the game.
Lets start with the Batarangs, when posible I upgrade both the strength and amount of Batarangs, as your progress in the game thugs appear in larger numbers. Sonic Batarang in invalable with the suidicide collars, but I feel the explosive feature doesn't help much. Other than in one of the challenges the Remote Control Batarang is useless, if you had the ability to "paint" targets that Batman want to take out, this Batarang upgrade does nothing for me.
Explosive gel is also invalable. the upgrade that detonates when a bad guy approches is also good, but the selective detoninate is not needed.
Bat claw/UltraBatclaw in much need throughout the game especially when looking for Ridder trohpies Arkham chonicles or takedowns.
Cryptographic sequencer is only needed to bring down electric barriers so I upgrades both abilities sasp to get it out of the way.
Line launcher is also good for quickly crossing gaps or areas inaccessible to Batman.
Armor is not needed at first but definatly by Posion Ivy and Joker fight you want full upgraded Batsuit armor.
Here is an of upgrade I would have liked to see.
Cape stun upgrade. Target stays stunned for longer period of time
