Are you trying to compare these two SMGs to other SMGs or SLRs?

Yeah, they are bad , the mp18 trench is decent because of the hipfire, but other than that, Automatico and Hellriegel and shotguns are much better. But overall Medic has good guns but not really meta.
Recon , Assault and Support have the better weapons, SMLE, Lebel , M95. Parabellum, ChauChat, M10 , Hellriegel, Automatico.

They're fine in my opinion. As someone that uses the MP18 and Ribeyrolle often, I haven't had too many issues dealing with SLRs unless its medium or long range. The Cei Rigotti and M1907 as I recall are barely beating out the MP18 in close quarters with 300 rpm. You miss a shot with one of those guns in close quarters against a MP18 your dead. You can't get away with as much with 300 rpm compared to something spraying 550 rpm. Keep in mind this is close quarters. Beyond that your playing with fire as an assault going up against a medic.

Ribeyrolles best Assault gun.

Well, it, the M1900 Slug, and the M12/P16, but if I had to pick only one to use at all times, it would be the Ribeyrolles.

Ultimately, if your goal is to do the best you possibly can (not going after service stars, and probably sacrificing some fun and/or challenge), I'd say that the Hellriegel is too good to really justify using the MP18, Ribeyrolles, or SMG 08/18 over it.

However, since I would actually like to retain some fun, I'd definitely go back to the Ribeyrolles instead of the Hellriegel after I'm done with the service stars in Assault. It's still a very solid choice and would be even more-so if the TTK changes would go through. The MP18 Trench is alright, and is the best/most accessible MP18 variant, but I think most people (me included) would rather run the Automatico M1918 Trench for hipfiring enemies back to the deploy screen.

Eh what? There are equal or better SLRs than the Chau, Auto .35 is still one of the best guns in the meta. The SLRs also dominate the statistically more relevant midrange compared to BAs.

The MP18 and Ribeye are "bad" because they don't do anything really great at short range (see shotguns or automatico), but then lose to most of the SLRs at the midrange. The tradeoffs are not worth it.

The .35 is a paper gun, I have over almost over 88 stars with the .35 Marksman and its not the "best" slr in the meta. Other SLR are better such as 1907, Fedorov, M1916 and RSC to some extend.

The LMG dominate the midrange, the fact alone that when a SLR hits 1 bullet at someone and doesn't suppress them makes it a bad choice.

Maybe we should be happy that Medic is not the meta like in BF4.

The other classes have much better choices for weapons.

How are you supposed to use the .35 Marksman? I had to for the weapon assignments and it was just agony.

The 4btk cutoff was just a little too long to be able to properly plink at people safely from a distance and the scope prevented any use within it's optimal range.
