If you have to ask, I'd say no. Huginn is a weak mech, you will likely regret it if you don't know exactly what you are getting into.
Always build on smurfys before you buy:

Heros are unique hard point layouts you can't get with c-bills, and a 30% c-bill boost to earnings in that mech, as well as a unique camo pattern they come with (that is only usable on that mech, cannot be replaced, but can have the colors changed).
Do not ever buy a hero mech on Thursday. They often announce hero mech sales on Friday, and you'll feel bad. Do not buy on Friday until after sales are announced. Also check the shop in-game for stealth sales that weren't well advertised. I believe smurfys now displays which mechs are for sale as well.
The top-tier hero mechs are:
Ember (Firestarter, Light)(4 ML, 4 MG, JumpJets!, 152 kph with speed tweak).
Firestarters are all good mechs.
Ilya (Cataphract) (3 UAC5s usually, although seeing more dual gauss).
Cataphract 3D is very competitive. So 2/3 builds good.
Dragonslayer (Victor) is also top-notch.
I do not know what the best hero medium is.
NOT the X5.
Yen lo Wang is fun, but a one trick pony, not very competitive.
I don't see many grid irons.
Best medium/the competitive Medium is the Shadowhawk, but it does not have any hero variants.
Some people enjoy and do well with the Misery and Heavy Metal. I'd consider those tier 2.
But you sound like a light fan.
I'd go Ember. It can Jump!
If you want a hero light. Easily the best hero light.
To be clear, the hero mechs are::
Tier 1 (Competitive mechs)
Ember (35 ton Firestarter)
Ilya Muromets (70 ton cataphract)(may be tier 2)
Dragonslayer (80 ton Victor)
Tier 2 (good/fun mechs)
Misery (85 ton stalker)
Heavy Metal (90 ton Highlander)
Oxide (35 ton jenner, cannot jump)
Firebrand (65 ton Jaeger)
Tier 3 (fun, okay for pugs)
Yen-lo-Wang (50 ton Centurian)
Grid Iron (50 ton Hunchback) (? not sure if it's as good as YLW, just guessing)
Jester (65 ton Catapault)(May be tier 2?)
Boars Head (100 ton atlas - may be tier 2?)
La Malinche (95 ton banshee, may be tier 2?)
Loup-de-Guerre (I think, 50 ton Trebuchet, not sure)
Protector (75 ton Orion)
Tier 4 (Bad)
X-5 (40 ton Cicada)
Death Knell (25 ton)
Fang (60 ton Dragon)
Pretty Baby (80 ton Awesome)
Flame (60 ton Dragon) (may be tier 3?)
Huginn (35 ton raven)
Don't get me wrong, some people like the mechs I've labelled tier 4 (bad), but you are far, far more likely to regret your purchase the further down my list you go, I believe.
