Stay for early project leadership opportunities and deeper experience or leave for better culture?

I'm a 2.5 yoe backed dev, currently still at my first company. Due to people above me leaving and us having a really tiny team I've become the "senior" developer in my company. My responsibilities have grown to doing project leadership, planning, architecture, infrastructure, along with general development and devops. Basically what I assume is senior stuff. I think I'm on top of things, and if I keep going at this rate ill be able to gain hands on experience with concepts I would have a hard time gaining elsewhere like leadership opportunities or building something from scratch. As well as the pay bump too. But I hate my workplace so much. My bosses are awkward, misogynistic, and incompetent to boot. They email me code for Christ's sake. The team is tiny so we never have enough people to work on things and development processes are almost nonexistent. I'm also trans, and the environment that I work in makes it impossible for me to come out without everything becoming more awkward than they already are. Is it a smart idea to stay at a shitty place for the experience and resume bump in the future? Or is it better to leave and find a better place?
