I use the standard assault rifle when I run as a Medic. I have got the Vampiric healgun as an alternative weapon.
And - useful tip - the Scanhammer can be used as a weapon; does 401 damage over a small cone chaped area in front of you - very useful for killing the smaller bugs in PvE which have 400 health (8 is my biggest multikill so far with it).
I tried out the so salled suppressor rifle; not very impressed I have to say. I can't see any significant advantage to using this; it has a bigger clip but lower damage per round. Just my opinion, some players like it.
The Grenade launcher might be worth a try if you have the Vampiric gun, not as good as the Assault's plasma cannon but can be effective against groups of bugs. But you only get 20total ammo
As for Engineer; not sure to be honest as I don't play that class.
I'm at level 12 Assault and have picked up an awesome Purple "Omnidevastator" Assault Rifle as a random loot drop, does 52 damage per round instead of the defauilt 40, and has a 1.8 headshot multiplier instead of the usual 1.5 - useful for the Terrorclaws etc. Very nice it is too, but I had to wait until rank 12 to use it.
