First off, I just purchased Ramos and played him for the first time today. That said, I have a fair amount of experience with Malifaux and have played against or with most of the possible crews.
In defense of Ramos, I found his ability to summon one or more Electrical Creations per turn significant, especially with the help of a Mobile Toolkit. They do 1 wd automatically when they move into base contact for the first time, then for a single action they can deal 3 dg within 2 inches... The beauty is that there is no resist for the 3 dg. Now if you summon two of these bad boys you can deal 8 dg to non-armored units...
The Steamborg Executioner I have used in my Hoffman crew and also with Ramos. I love this model. While he doesn't have the staying power of the Peacekeeper, his offensive abilities are spectacular. One thing that I personally love is his ability to bypass defensive walls to get to more important targets. You can turn a (1) melee attack into a 11 inch charge behind your enemy's line. Which would take up your melee expert action and allow you to flurry whichever model you charged... Deadly.
Anyways here is a little insight from my experience. As far as Strategies and Schemes, I like the Arcanist only scheme Sabotage. Especially if your strategy requires you to move over to the other side of the board.
Good Luck.
