The Recon Cloak more closely resembles a shield. It can be activated permanently, but takes "damage" as it is hit. You are only forced to uncloak when it has taken as much damage as it can. As a "shield," it has no resistances, but has rather high shield-health. It should be enough to withstand a hit or two from common LD weapons.
The Guardian Shield should have the maximum resistances from all damage types and statues, plus maximum shield health (like Omega Shell). It is presently a tad too weak to be really competitive. If a little balancing is necessary, one could either take away its abilities (+sword ASI, +bomb CTR, -gun ASI) or reduce the health it grants the user.
Opinions?
Letting the recon cloak tank isnae what we need; they just need to remove the "breaks completely when some AAr snipes you". As it is, a single lucky swing or shot leaves the recon completely defenceless against strikers whose booster is otherwise "unbreakable" meaning that as soon as anything breaks the shield, you die. They dnon't need to be able to tank hits cloaked, they just need to be able to re-cloak after a hit.
The guardian shield is a "tad weak" already, but removing their already abysmally low bonuses to improve it even more? Might as well just do nothin'. Guardians are in need of changing, but it certainly doesnae involve removing the two pathetic buffs they already have.
