Welcome to Librarium Online!
I'm still finishing up my first list and I noticed a heavy weapons squad with three lascannons is the same price as a 5 man stormtrooper squad with two meltas.
So the question is which would you rather have and why?
Well... as is, neither. If you put a gun to my head I think I'd go with the HWS, simply because a 5 man stormie squad with meltas is going nowhere if they don't have a transport.

Veterans, 3 meltas, chimera. Alright not very original nowdays but really I agree with SimSnow, if pressed the lascannons, if only because you're likely to have at least some return your investment, stormies have really been wrecked by the new codex, even with DS (how I used to play them in the old dex) they are pretty poor, and when compared to vets and their options it's hard to justify taking them.
Stormtroopers: They give you added mobility with an accurate deepstrike, can be more effective at busting heavy AV with meltas vs. LCs, and honestly a 5 wound unit with 4+ saves will offer slightly better durability than a 6 wound unit with 5+ saves especially when you take Instant Death for W2 bases into account.
Plus Kas'rkin models are amazingly awesome in every way.
I use 2 lascannon HWSs amd a melta stormie squad in my 1500 point list and have no problems with vehicles below the size of a land raider, and even then the LR's are usually gone when my stormies drop in.
So I choose both.

Neither are particularly good. Stormies are overpriced with failsauce crapshot lasguns and a single HWS is stupidly easy to get blasted.
En masse, HWS would be better, but cheap meltas and S10 ordnance wins out when it comes to tank busting.
Nothing they get is really worth the price tag. Scouting with a Chimera isn't too bad, but that's it.
