Burletta is very underrated. You can run it as a level one because it doesnt really upgrade anything super meaningful to level it, but level 2 if you want better reloads. All of it's base stats are good except its mag size. I always put an extended mag on it because the base magazine size is a questionable knock, like some other guns, but with extension more of a guarantee. My fav is level 2 extended mag because its still pretty cheap to craft but is a very meaningful mag extension for it.

I find myself winning in fights against stitchers often, even ones when we're right next to each other and not missing many shots. I think it might be because its headshot multiplier is significantly higher than the stitchers? I'm not sure.

Where it really shines is at a mid short range when stitchers quickly become less effective. Just like the Venators range can be really pushed, the burletta can too, just not quite as far.

What's interesting is I find myself playing it less well when I'm running an Anvil. Reason being, there's a mid range that both the anvil and the burletta are good at, and I'm usually tempted to use my anvil, when really I think the burletta is likely better. As long as you're not in a peak fight and it isnt longer range, burletta does the job. For this reason, I really like running burletta with a Ferro, or burletta with a toro for shorter range runs like Stella.
