Well; when RoB came out, there was a lot of protest about 'OP' Corvus armour.
How are people standing on the matter now?
For me, it's certainly a non-problem. The sensory bonus is of course great, and the agility bonus really sweet when flying a jetpack, sneaking around, or dodging. But armour's main job is to stop stuff hurting the wearer, and this is where the suit really comes up short.
Firstly, it's disadvantageous against hordes. You can't dodge them, and wearing Corvus just means taking more damage every time you take hits. Now most of the time I've been damaging PCs with hordes, perhaps 1-5 damage has been getting through with each blow, with an emphasis on the lower end of the scale. So PCs in Corvus have been taking *substantially* more damage from hordes. All the while. Whereas those in meatier armour have been escaping the fray having taken 25% or so less damage, which has been quite significent, because those extra wounds from Corvus are very regularly resulting in more wounds than the Apo can heal.
Seeing as Horde combats are about 50% of my combats, this is a pretty major disadvantage.
Against master-level foes, the difference isn't so great. The Corvus is certainly a better bet against foes with high power ranged weapons which all but moot a point or two of extra armour and need to be dodged, but it's not a major imbalance.
Against elites who typically get 3-8 damage through to the PCs, the Corvus armour means players are struggling after 5 hits instead of 4. The Agi bonus is of little help against melee foes, so the armour is clearly disadvantageous here to a degree.
Where I am noticing a difference is in critical wounds. Those in Corvus are certainly accumulating a lot nastier critical levels.
All in all, I'm seeing Corvus' main advantage to be non-combat and utilitarian in nature: Better jet pack use, climbing, stealth and awareness checks. Although it's an advantage against powerful shooty foes, Corvus is a little worse in the majority of melees than later models, and a rather large disadvantage against hordes.
What are your experiences?
