Worth Lateralling? Grinding in Mid-BB Group

I'm in a mid group mid BB that has had rare UMM/MF exits and most people are great but several seniors suck ass (typical shit— late to review, bad write ups, lazy VP who’s useless, etc). But I luckily got staffed with extremely good responsibility (building / owning the model, associate lateraled elsewhere and no one else was staffed on) and a good deal (but complete luck of draw may just be me on no name pitches next two years), and I've been working consistent 1-5 AM's several nights a week (though Saturdays get respected) with some BS pitches on top for a group that gets little M&A mandates.If I have a line into really good sweatshop groups (GSTMT, etc) think it's worth lateraling if I am working a lot anyway? I'm sure the extra work I'd do will still be a huge change in lifestyle but I want the most control over exits and try going to a HF / top GE shop.My group has exited to HFs and MFs but not often at ALL and not exactly name brand or ones I'd want to work at (basically no name or super super grindy). Basically wanna lateral, recruit well, and then coast / try to survive. Not "really" a FaceTime culture here( though it's there a little) but being in office 5 days a week would be brutal.
