Accept Big 4 Tax Offer or keep looking

I'm currently doing my junior year internship at a Big4 doing tax. I realized I no longer want to be an accountant and after working on the VC/PE team, I am interested in working in VC down the line. I want to get into IB as a stepping stone for that in case I don't want to do VC but something else finance related. I am wondering if I should accept my full time offer to work in tax with my firm or to turn it down try to land an IB role at a middle market bank. I requested to be switched to advisory, but they said it's unlikely they can switch me now. My management told me that they can try to switch me after I have around 2yrs of work experience with the firm. I'm an Economics & Accounting major w/ 3.7GPA, non target school, hoping to work in the Bay Area. Thank you in advance for any advice.
