Stay with current boutique after graduation or BB/MM?

Hey guys, so I'm a rising junior in california at a non-target (think top 75 institution) interning at a boutique investment bank. I'm going through the 2018 SA recruiting process and I know I want to be at a larger firm next summer, but I'm conflicted about what to do post-grad. A VP at my current firm who used to work at Lazard and Goldman said if he's still at the boutique in 2019 then "you have a job. I like your work and you helped with valuation material on XYZ deal when **** (current associate) dropped the ball." The idea of knowing I have a job post grad is tempting.

I don't know if the pay is above street for california, but another associate at my shop told me he pulled in $230k last year ($100k bonus and $130k base). An analyst can expect 80k base and 30-50k bonus. The hours are the most attractive part--50/60 hour weeks maximum for analysts, every so often 70/80.

I'm tempted to forgo going to a larger firm and just staying with them post-grad and then leveraging business school to go to VC/F100 M&A. As you can see, my thoughts are pretty scattered here. Any input would be much appreciated.
