There will be different instances in which different PaP'd(Pack a Punched) guns will be effective, and it is mostly opinion when asking "What is the best non wonder weapon to PaP in Black Ops?".
I would start to eliminate the weapons that shouldn't be PaP'd. All of the wall weapons i would suggest to not PaP, unless it is an AK74u, Stakeout, or MP40. I say these guns because the AK74u, Stakeout, and MP40 all have considerable strength when PaP'd, and they rack up points BIG time. Now, if you aren't a skilled player(one who consistently runs "trains" or small-knit loops) who is also someone who stays near these weapons to grab ammo. Having the ability to be able to buy ammo will keep you going until you get something that can help, like a Max Ammo power up.
Out of the box guns, i would suggest: Commando, Galil, Ballistic Knife, RPK, HK21.
Commando: It gets more ammo, much more powerful, and will rack up the points spent to PaP it.
Galil: Better sight, stronger, and much more ammo.
Ballistic Knife: This weapon is well paired with the special knife on the maps(I.E. Sickle or Bowie Knife.). It heals people who might not be reachable in time, and can knife for kills, which means more points than usual.
RPK and HK21: Both of these guns have different attributes. HK21 is stronger, shoots much slower, while the RPK shoots much faster and slightly weaker. Either is fine, as they have a lot of Ammo. RPK PaP'd has 625 rounds, while the HK21 has 850, i think. The HK21 i suggest to use with Double Tap perk, to increase speed, or else you'll be shooting too slow to deal any real damage.
Now, any gun PaP'd is decent, but these were the ones i use most often(that are not wonder weapons). My personal favorites are the AK74u, for the strength and consistency of ammo. The RPK, having lots of ammo to start with along with it's fast fire rate, and the Galil for overall being a great gun PaP'd.
Hopes this helps, as i wasn't sure what you entirely meant by the question. Statistics of the PaP'd guns can be found on other sites, so if you were looking for sheer strength in each bullet, or if you prefer faster fire rate, etc.
In keno der toten, the best guns possibly are ray gun pack a punched, in moon it's possibly wave gun pack a punched, but the three best weapons would be ( pack a punched) ray gun, wave gun, ak 74
In my opinion it is the AK74U or the Thunder gun [zeus cannon]
Ray Gun

You have to have at least 950 points to get a gun from the mystery box in black ops zombies.
Black Ops 2 Zombies is harder but also way funner than Black Ops Zombies.
a MAC 11 or an AK47
