ok to end this
Stock Ion is Faster. Due to Better Eye logic and settings and the Ramping

. if you are NOT gonna upgrade your Gun get an Ion.
Upped the Wrath is better. stock Cocker threads = Limitless barrels +Stock clamping neck + stock Qev play a part. the T-board + Ultra chip Drasticly improves Speed + efficiency. delrin ram/bolt Reduce kick to almost Nothing. and new trigger will reduce side-side play and Increase speed. about 160$ in ups.
With the new UPs for the Ion. Lucky's cocker Reciver,new bolts,new frames, and New boards and bodys, it will all come down to personaly prefrence. and How Much you want to Spend in Upgrades. to Fully up an Ion with the latest goodies it will cost you well into $400
so math wise
ION 400<ups>+250<ion> = $650 roughly endgame
Wrath 180<ups>+250<wrath> = $430 roughly endgame
Look at what you spend, you Might be able to buy sumthing Nicer.
so like Many, other Vs threads it all comes down to Personal Prefrence,and how much you want to spend End Game. test and try and you'll get what you like.
btw, i havnt used a Omen 2.0 and ive only seen 3 , but thats me ^^
