Ok, more time to post
Pomson: It's use depends mostly on whether or not it does damage. Right now, I believe it does, because we've had other weapons that have said "On-hit" but you have to explicitly say you do less damage, especially since it's a shotgun and not some new weapon type.
Anyway, the main thing for me is the fact that it pierces. The laser pistol that the Soldier got became one of my favorite weapons to use when I wasn't carrying a banner just because of that. The fact that it's a primary means that it'll be easier to use the (I'm guessing) slow projectile speed in a fight. The fact that you can interrupt ubers right before they reach your gun is just icing on the cake.
Eureka Effect: People have pretty much gone over everything here. Getting spammed down and it's only a matter of time before that crit sticky gets detted? Eureka Effect! Spy got your teles? Eureka Effect! Teammates need help at spawn? Eureka Effect! Seriously, this is the first weapon that gives you a major advantage if you focus on a building that isn't the Sentry. In this case, it's the Teleporter. No matter where you are the map, you can plop down a Teleporter, teleport away, and then be back within 10 seconds with 200 metal. Not only is it a great team weapon, but it's going to bring back waves of sneaking teleporters behind enemy lines. I'm hoping they eventually come up with something that works as well with Dispensers besides the Deus Ex weapons.
Third Degree: This weapon is potentially powerful, and it's sad that it's an anti-Medic weapon only. Basically, if you get a crit swing with it while aiming at the Medic's patient, you'll crit the Medic as well. Otherwise, it's not that good unless the Phlogistnator provides it's crit boost to all of your weapons, kind of like the Soda Popper. I wish it did more damage than the average melee weapon. Thank you Yeef for making me realize how well this combos with the Detonator as well.
Phlogistnator: If you don't think this is awesome then either you don't play Pyro or you only play defensive Pyro and never switch from the Axetinguisher/Mailbox or Homewrecker.
Manmelter: It looks like a Flaregun, but because the weapon type is "Particle Smasher" It probably fires like the laser pistol, continuing Valve's outreach program of giving Soldier type weapons to the Pyro. If you can't extinguish teammates with right click while using it you run the risk of wasting crits to extinguish multiple teammates (unless you're carrying one of the other flamethrowers), and then that means you'll primarily use it as an anti-Pyro weapon during team fights. Since it doesn't pierce or set things on fire like all the other particle weapons, it's sadly the weakest new weapon out of the bunch. Unless, of course, it reloads freakishly fast or has a clip of at least 8 shots. Then I can say it's better than the Third Degree.
I really wish it did something to enemies that were already on fire, but I guess in their minds that since the Flaregun sets enemies on fire, let's give Pyro a water pistol that extinguishes friendlies on fire. But water isn't very fun, so let's use lasers.
In the end, these weapons solidify that he's an odd flanker and a great support, and not much else. And while I'm glad that they're giving us new toys while being mindful so that we can mix and match them with our original stuff, I am not happy that they're making more sets that aren't very synergistic with themselves. More like the Demo's 1,001 set and less like the Heavy's Made Men please.
