Keep in mind that the raven is more of a support light - ECM, narc quirks, long range poking, and comparatively slow (for a light) without upgrading the engine. To make it fast, you'll need to sink a fairly hefty amount of cbills into it (by my bankroll anyway).
The huginn however, is more of a harasser role, and there are raven builds that mount AC20 that might fit your needs.
The cicada is a lot faster, but no ecm (that i recall). Somewhat larger too. It can also do long range poking, but more frequently focuses on close range strafing.
For your purposes... they are about equal overall. If all you do is follow heavies to
cherry pic, assist, you don't actually need a lot of speed. But you do need/want armor. ECM is also helpful in that overall scenario, because exposure is practically guaranteed. Long range weapons are also useful because in puglandia, heavies spend 2/3rds of their time hanging back sniping and crowding each other around one piece of cover.
Mind, too slow and you wont be able to respond to developing situations well (heavies are not going to make it back to base in time to prevent a capture, etc. That is a job for lights/med/fast mechs) or protect against more agile lights that are harassing YOUR heavies - heavies are juicy kills, but enemy lights and meds will treat you as a priority threat... something to deal with/leg quickly before flanking that heavy.
So... personally I feel the Raven is actually more versatile, in terms of what it can offer the group. The cicada is more versatile in terms of armament, but its role is more limited imho.
I mean, you say "scout" mech... but it doesn't sound like you play scout mode FW (here are no heavies in scout mode FW)... and your preferred playstyle doesn't involve scouting at all... so.... ??
